First embodiment

If m pieces of data are included in original information to be subjected to security protection, according to an information encryption scheme provided in the related art, when the original information is encrypted, processing on each of the m pieces of data is the same, for example, for a character string "I low YOU", a typical encryption manner in the related art is to add k to each value of the character string, for example, in one scheme, a value of k is 1, a ciphertext obtained after encryption is "J MPWF ZPV", it is easy to see that comparing the original information and the ciphertext, since processing on each piece of data is the same, the same data in the original information is also the same in the ciphertext. For this encryption scheme, the mapping relationship is simple, once the ciphertext is intercepted, the risk of being decrypted is very high, which seriously threatens the information security of the user, and in order to solve this problem, this embodiment provides an information encryption scheme, please refer to the flowchart shown in fig. 3:

s302: the encryption terminal obtains original information to be encrypted, obtains a decimal data number sequence corresponding to the original information, and determines the data number in the decimal data number sequence.

In this embodiment, the encryption terminal may be any one of a mobile phone, a desktop computer, a notebook computer, a tablet computer, and the like. The information to be encrypted may be any one of integer, long integer, character, string, etc. After the encryption terminal acquires the original information, the encryption terminal may acquire the decimal data number sequence corresponding to the original information, for example, in an example of the present embodiment, the encryption terminal may convert the original information into the decimal data number sequence in accordance with an ASCII table. Here, the description will be given with the original information as a character string "ILOVE YOU":

after the encryption terminal acquires the original information to be encrypted, namely the character string "I LOVE YOU", the encryption terminal can query the ASCII table to convert each character (including a blank space) in the character string into corresponding decimal data, and form a sequence of the data according to the corresponding position of the data in the character string, wherein the sequence of the data is a decimal data sequence. The conversion result for the string "I level YOU" is {73,32,76,79,86,69,32,89,79,85 }.

It can be understood that when converting the character string in the original information according to the ASCII table, the original character string contains spaces for how many characters there are, and there are many decimal data after the conversion. And the arrangement position of each decimal data corresponds to the arrangement position of each character in the character string.

After the encryption terminal determines the sequence of decimal data, the encryption terminal may determine how many decimal data are in total in the sequence of decimal data, the number of decimal data being related to the setting of subsequent joseph ring parameters.

S304: and the encryption terminal sets Josephson ring parameters (N, K, M) according to the determined data number, and generates a Josephson ring number sequence containing N decimal data according to the Josephson ring parameters.

After the number of data in the decimal data sequence is determined, the joseph ring parameter (N, K, M) may be set according to the number of data, where the value of N is equal to the number of data in the decimal data sequence, for example, for the decimal data sequence obtained by converting the character string "I low YOU", the number of data is 10, and the value of N in the joseph ring parameter is 10.

The joseph ring is briefly described below:

the josephson ring (i.e., the josephson problem) is a mathematical application problem: n persons (numbered 1, 2, 3.. N, respectively) are known to sit around a round table. Counting from 1 to M from the person with the number K; the next person counts again from 1 and the person counting to M continues to be listed … … in this order until all people around the round table are listed.

With further reference to fig. 4, fig. 4 shows a clock ring, in which 12 (i.e., parameter N) digits from 1 to 12 are arranged in a ring, and assuming that the number of the digits "4" (i.e., parameter M) is listed from the number 1 (i.e., parameter K), the digit "4" will be reported to "4" in the first round of the number of the digits, so that the listed digit "4" forms the first bit of data in the joseph ring. In the second round of counts, the digit "8" will report to "4", thereby forming a dequeue, and the dequeue digit "8" will constitute the second bit of data … … in the Joseph ring sequence, which will cycle through until all data are dequeued, resulting in a Joseph ring sequence as follows:

{4,8,12,5,10,3,11,7,6,9,1,2}；

therefore, by setting the parameter N of the joseph ring according to the number of data in the decimal data sequence, it is possible to ensure that the number of data in the generated joseph ring sequence is the same as the number of data in the decimal data sequence. In this way, when the josephson ring sequence and the decimal data sequence are subjected to the synthesis processing, for each data in the decimal data sequence, there is one data corresponding to the direction of the josephson ring sequence at the corresponding position.

It should be understood that if any one of the three joseph ring parameters (N, K, M) changes, the resulting joseph ring sequence will be different. In this embodiment, the value of the parameter N in the josephson ring parameter is determined, but the values of the other two parameters can be determined by the encryption terminal itself.

In the decimal data sequence {73,32,76,79,86,69,32,89,79,85}, the encryption terminal in the embodiment sets the joseph ring parameters to be (10,0,3), and the joseph ring sequence generated by the encryption terminal is {3,6,9,2,7,1,8,5,10,4 }.

S306: and the encryption terminal synthesizes the decimal data sequence and the Joseph ring sequence to obtain a synthesized sequence comprising N decimal data.

After the encryption terminal generates the josephson ring number sequence from the josephson ring parameter, the synthesis process may be performed on the josephson ring number sequence and the decimal data number sequence. It should be understood that, as for the 1 st data in the decimal data sequence corresponding to the 1 st data in the joseph ring sequence, the 2 nd data in the decimal data sequence corresponding to the 2 nd data in the joseph ring sequence, the 3 rd data in the decimal data sequence, which is successively analogized to … … corresponding to the 3 rd data in the joseph ring sequence, the nth data in the decimal data sequence corresponding to the nth data in the joseph ring sequence, when the synthesis processing is performed on the joseph ring sequence and the decimal data sequence, the nth data in the synthesized data sequence can be obtained by synthesizing the nth data in the joseph ring sequence together with the nth data in the decimal data sequence.

In some examples of this embodiment, the encryption terminal may directly combine the nth data in the joseph ring sequence with the nth data in the decimal data sequence to form a new decimal data, for example, when the decimal data sequence {73,32,76,79,86,69,32,89,79,85} and the joseph ring sequence {3,6,9,2,7,1,8,5,10,4} are combined, the encryption terminal may combine "73" and "3" (i.e., 03) to form "7303", so that "7303" becomes the first data in the combined sequence. The "32" and "6" (i.e. 06) are combined into "3206", and "3206" is the first data … … in the synthesized sequence, and by deducing the class, the synthesized sequence {7303,32067609,7902,8607,6901,3208,8905,7910,8504} composed of ten data can be obtained.

In other examples of this embodiment, the encryption terminal may perform an operation on the nth data in the joseph ring sequence and the nth data in the decimal data sequence to obtain the nth data in the synthesized sequence, where the operation includes some relatively complex formula operations or may be a simple four-way operation, for example, in an example of this embodiment, the encryption terminal performs a synthesis process on the joseph ring sequence and the decimal data sequence by using an addition operation: the encryption terminal adds "73" and "3" to obtain data "76", takes "76" as the first data in the combined sequence, "32" and "6" to obtain data "38", takes "38" as the second data … … in the combined sequence, "85" and "4" to obtain data "89", and "89" is the last data in the combined sequence. Therefore, by this way of combining processing, the encryption terminal will get the combined series {76,38,85,81,93,70,40,94,89,89 }.

It should be understood that in other examples of the embodiment, the encryption terminal may also perform operations such as subtraction, multiplication or division on the nth data in the joseph ring sequence and the nth data in the decimal data sequence, or perform more complex operations, for example, in an example of the embodiment, the encryption terminal performs the operation by a _n *5-b _n 3+2 to synthesize the nth data in the Joseph ring sequence and the nth data in the decimal data sequence, wherein a _n Is the nth data in the Joseph Ring array, and b _n Is the nth data in the decimal data array.

S308: and the encryption terminal carries out secondary synthesis on the synthesized sequence and the Joseph ring parameter to obtain encryption information.

After the encryption terminal synthesizes the joseph ring number sequence and the decimal data number sequence and obtains a synthesized number sequence, the encryption terminal can carry out secondary synthesis on the synthesized number sequence and the joseph parameter so as to obtain final encryption information. In this embodiment, the encryption terminal performs secondary synthesis on the synthesized sequence and the joseph parameter, mainly carries the joseph parameter in the encryption information, so that the decryption terminal can obtain the decryption key, that is, the joseph parameter, from the encryption information after obtaining the encryption information.

In some examples of this embodiment, the encryption terminal may insert joseph parameters into the data of the synthesized sequence to form a sequence including N +3 data, for example, in one example of this embodiment, the encryption terminal may insert three of the joseph parameters into the forefront of the synthesized sequence, for example, in such a way that the synthesized sequence {76,38,85,81,93,70,40,94,89,89} and the joseph ring parameters (10,0,3) will be twice synthesized to obtain a new sequence {10,0,3,76,38,85,81,93,70,40,94,89,89 }. In another example of this embodiment, the cryptographic terminal may insert three of the josephson parameters into the last of the synthesized sequence of numbers, for example, in this way, the synthesized sequence of numbers {76,38,85,81,93,70,40,94,89,89} and the josephson ring parameters (10,0,3) will be twice synthesized to obtain a new sequence of numbers {76,38,85,81,93,70,40,94,89,89,10,0,3 }.

Of course, in some examples of this embodiment, the encryption terminal may also insert three parameters of the josephson ring parameters into the composite sequence separately, for example, insert N into the first data and the second data of the composite sequence as the second data of the encryption information, insert K into the 4 th data of the composite sequence as the 6 th data of the encryption information, and insert M into the last data of the composite sequence as the last data of the encryption information, for example, by the twice-synthesis, the encryption terminal may obtain the encryption information {76,10,38,85,81,0,93,70,40,94,89,89,3 }.

After the encryption of the original information is completed and the encrypted information is obtained, if the encryption terminal needs to transmit the encrypted information to other objects, the encryption terminal can transmit the encrypted information to a corresponding receiving terminal.

In the information encryption method provided by this embodiment, the joseph ring number arrays with the same number of data are generated according to the number of data in the decimal data number array corresponding to the original information, so that the joseph ring number arrays are used as an encryption matrix for encrypting the decimal data number array corresponding to the original information, the processing modes of each data in the decimal data number array are different, and the difficulty in decoding the encrypted information is improved. In addition, the josephson ring parameters can be carried in the encrypted information and transmitted to the information receiving end, so that the decryption terminal of the information receiving end directly obtains the josephson ring parameters under the condition of knowing the decryption rule, and generates a josephson ring number sequence, thereby realizing decryption of the encrypted information and obtaining the original information. The Joseph ring parameters can be set by an encryption terminal of an information sending end, different Joseph ring parameters can be set in different information transmission processes, the problem that information safety is reduced due to the fact that fixed Joseph ring parameters are used for a long time is solved, and information safety is improved.

Second embodiment

The present embodiment provides an information decryption method corresponding to the information encryption method in the first embodiment, please refer to the flowchart of the information decryption method shown in fig. 5:

s502: and the decryption terminal acquires the encrypted information to be decrypted.

It should be understood that the decryption terminal may receive the encrypted information through the network, for example, the mobile phone of user a and the mobile phone of user B perform encrypted communication, and after the mobile phone of user a encrypts the original information to generate the encrypted information, the encrypted information is transmitted to the mobile phone of user B through the network, in which case the mobile phone of user B obtains the encrypted information from the network. Of course, those skilled in the art will understand that the way of the decryption terminal to obtain the encrypted information also includes many others, for example, copying the encrypted information from other terminals through a usb disk, etc.

In addition, it should be noted that, in this embodiment, the encryption terminal that encrypts the original information and the terminal that decrypts the encrypted information may be the same, for example, after one terminal decrypts the original information to obtain the encrypted information, one terminal may send one copy to the other terminal, and at the same time, one copy of the encrypted information may be retained for subsequent viewing. When the terminal views the encrypted information, it needs to operate as a decryption terminal. In addition, in more scenarios, during the encrypted communication between two terminals, any one of the two terminals needs to be operated as both an encryption terminal and a decryption terminal. For example, in fig. 6, the first terminal 601 performs bidirectional encrypted communication with the second terminal 602, and after the first terminal 601 transmits the first encrypted information to the second terminal 602, the second terminal 602 is likely to need to transmit the second encrypted information to the first terminal. Then, during the communication of the first encrypted information, the first terminal 601 operates as an encryption terminal and the second terminal 602 operates as a decryption terminal, but during the communication of the second encrypted information, the first terminal 601 operates as a decryption terminal and the second terminal 602 operates as an encryption terminal.

It is assumed in this embodiment that the encrypted information acquired by the decryption terminal is {76,38,85,81,93,70,40,94,89,89,10,0,3 }.

S504: and the decryption terminal disassembles the encrypted information to obtain Joseph ring parameters (N, K, M) and a synthesis sequence.

After the decryption terminal acquires the encrypted information, the encrypted information can be disassembled, so that josephson ring parameters (N, K, M) and a synthesis sequence are obtained. As can be seen from the description of the first embodiment, the josephson ring parameter may be inserted into the synthesized sequence to form encrypted information, and therefore, after the decryption terminal knows the insertion rule of the josephson ring parameter, the encrypted information can be split, so as to obtain the synthesized sequence and the josephson ring parameter.

For example, assuming that the encryption terminal inserts three parameters of joseph parameters into the last of the combined sequence of numbers in the encryption rule agreed by the encryption terminal and the decryption terminal, the decryption terminal may extract three data from the last of the encrypted information as joseph ring parameters, respectively. For example, for the encrypted information {76,38,85,81,93,70,40,94,89,89,10,0,3}, the josephson ring parameter disassembled by the decryption terminal is (10,0,3), and the composite number is {76,38,85,81,93,70,40,94,89,89 }.

It is needless to say that in the encryption rule agreed by the encryption terminal and the decryption terminal, the way of disassembling the encrypted information may be other ways, for example, if the encryption terminal inserts three parameters of joseph parameters into the head of the synthesized sequence, the decryption terminal may extract the first three data of the encrypted information as joseph ring parameters. For other ways, they are not described in detail here.

It is understood that, after the decryption terminal disassembles the joseph ring parameters and the synthesized sequence, the decryption terminal may perform preliminary verification on the encrypted information in combination with N in the joseph ring parameters to determine whether the encrypted information is possibly tampered: the decryption terminal can determine whether the number of the data in the synthesized sequence is equal to N, because the number of the data in the synthesized sequence is equal to N under normal conditions, once the decryption terminal finds that the value of N is not equal to the number of the data in the synthesized sequence, the decryption terminal can determine that the encrypted information acquired by the decryption terminal has been tampered, and the encrypted information is not encrypted by the encryption terminal. However, if N in the josephson ring parameter is the same as the number of data in the synthesized sequence, the decryption terminal cannot be sure that the encrypted information is not tampered, and after all, the security of the encrypted information can be preliminarily verified by the verification method.

S506: the decryption terminal generates a Joseph ring number sequence containing N decimal data according to the Joseph ring parameters.

After the decryption terminal determines the joseph ring parameters (N, K, M), a joseph ring sequence consisting of N data may be generated from the joseph ring parameters (N, K, M), e.g., for the joseph ring parameters (10,0,3), the decryption terminal may generate the joseph ring sequence {3,6,9,2,7,1,8,5,10,4 }.

S508: and the decryption terminal disassembles the synthesized number sequence according to the Joseph ring number sequence to obtain a decimal data number sequence containing N decimal data.

After the decryption terminal acquires the Joseph ring number sequence, the synthesized number sequence can be analyzed according to the Joseph ring number sequence, so that a decimal data number sequence is obtained. The nth data in the synthesized sequence is synthesized by the nth data in the decimal data sequence and the nth data in the joseph ring sequence, where the synthesizing process may be some more complex formula operation processes or may be a simple four-way operation process, for example, in some examples of the present embodiment, the nth data in the synthesized sequence is obtained by adding the nth data in the decimal data sequence and the nth data in the joseph ring sequence, and then in order to restore the decimal data sequence according to the synthesized sequence and the joseph ring sequence, the decryption terminal may perform an inverse operation of the synthesizing process according to the nth data in the synthesized sequence and the nth data in the joseph ring sequence, so as to obtain the nth data in the decimal data sequence. For example, in the case where the synthesis process is an addition process, the decryption terminal subtracts the nth data in the josephson ring number sequence from the nth data in the synthesis number sequence, and takes the calculated difference value as the nth data in the decimal data number sequence.

Taking the joseph ring number as {3,6,9,2,7,1,8,5,10,4} and the synthesis number as {76,38,85,81,93,70,40,94,89,89}, the decimal data obtained by the decryption terminal is {73,32,76,79,86,69,32,89,79,85 }.

S510: the decryption terminal converts the decimal data sequence into the original information.

In some examples of the embodiment, after obtaining the decimal data sequence, the decryption terminal may convert the decimal data sequence into the original information, for example, the decryption terminal may perform conversion on the decimal data sequence according to an ASCII table, and for the decimal data sequence {73,32,76,79,86,69,32,89,79,85}, the decryption terminal queries the ASCII table to obtain the original information, i.e., the character string "I LOVE YOU".

The information decryption method provided in this embodiment is used in cooperation with the information encryption method provided in the first embodiment, and the josephson ring number array is used as an encryption matrix for encrypting the decimal data number array corresponding to the original information, so that the processing modes of each piece of data in the decimal data number array are different, and the difficulty in deciphering the encrypted information is improved.

And moreover, the Joseph ring parameters can be adjusted at any time, so that the problem of information safety reduction caused by long-term use of fixed Joseph ring parameters is solved, and the information safety is improved.

Third embodiment

In order to make the advantages and details of the information encryption method and the information decryption method provided by the present invention more clear to those skilled in the art, the process background management method will be further described in this embodiment with reference to examples: first, assuming that the terminal in this embodiment is a mobile phone, as shown in fig. 7, the mobile phone 700 communicates with another tablet computer, and assuming that the mobile phone 700 needs to transmit a file to the tablet computer, the information contained in the file is sensitive and needs to be highly secured, therefore, the mobile phone 700 and the tablet computer perform encrypted transmission on the file to be transmitted based on the information encryption and decryption scheme provided in the foregoing embodiment. Please refer to the interaction flow chart between the mobile phone 700 and the tablet pc provided in fig. 8:

s802: and the mobile phone converts the acquired original information into an ASCII value to obtain a decimal data array.

Assuming that the file to be protected by encryption includes the content "Public key", the mobile phone may obtain the decimal data number corresponding to the part of content as {80,117,98,108,105,99,32,107,101,121} by looking up the ASCII table.

S804: the handset determines the number of data contained in the decimal data sequence.

After the decimal data sequence is obtained, the mobile phone can determine that the number of data in the decimal data sequence {80,117,98,108,105,99,32,107,101,121} is 10.

S806: the mobile phone determines the Joseph ring parameters according to the number of data in the decimal data array.

Because the number of data in the decimal data array is 10, the mobile phone can determine that the value of N in the joseph ring parameter is 10, and for the other two parameters, the mobile phone sets them to 1 and 3, that is, the value of K is 1, and the value of M is 3, so that the formed joseph ring parameter is (10,1, 3).

S808: the handset generates a josephson ring sequence.

Based on the joseph ring parameters (10,1,3), the handset can generate joseph ring sequence, {4,7,10,3,8,2,9,6,1,5 }.

S810: the mobile phone synthesizes the Joseph ring number sequence and the decimal data number sequence based on addition operation to obtain a synthesized number sequence.

After obtaining the joseph ring number sequence, the mobile phone may synthesize the joseph ring number sequence and the decimal data number sequence obtained by converting the original information, and in this embodiment, the mobile phone adds the nth data in the joseph ring number sequence and the nth data in the decimal data number sequence to obtain the nth data in the synthesized number sequence. Thus, the handset can obtain the composite series {84,124,108,111,113,101,41,113,102,126 }.

S812: the mobile phone inserts the josephson ring parameters into the synthesized sequence of numbers to obtain the encrypted information.

After obtaining the synthesis sequence, the mobile phone needs to send the josephson ring parameters and the synthesis sequence to the information receiving end, i.e., the tablet computer, so as to enable the tablet computer to determine how the josephson ring sequence is generated. In other examples of this embodiment, the mobile phone may also give joseph ring parameters to the tablet computer through a separate channel, however, in this embodiment, the mobile phone may directly perform secondary synthesis on the joseph ring parameters and the synthesized sequence of numbers, so as to directly send the joseph ring parameters and the synthesized sequence of numbers to the tablet computer together, because in the case that other malicious attackers do not know about extracting the joseph ring parameters from the encrypted information, carrying the joseph ring parameters on the encrypted information can make them unclear which information in the encrypted information is encrypted information, which information is information for encryption, thereby confusing the other party and enhancing information security.

In an example of this embodiment, the handset may insert three of the joseph parameters directly into the last of the synthesized sequence of numbers, e.g., for the synthesized sequence of numbers {84,124,108,111,113,101,41,113,102,126} and the joseph ring parameters (10,1,3), a new sequence of numbers {84,124,108,111,113,101,41,113,102,126,10,1,3} will be synthesized twice.

S814: the mobile phone sends the encrypted information to the tablet computer.

After the encrypted information is obtained, the mobile phone completes the encryption of the original information, and the encrypted information obtained through encryption can be transmitted to the tablet computer. Because the original information in the encrypted information is encrypted layer by layer, the original information is difficult to decipher even if being intercepted by a malicious attacker.

S816: and finally extracting three Joseph ring parameters and a synthesized sequence from the encrypted information by the tablet computer.

The tablet computer obtains encryption information {84,124,108,111,113,101,41,113,102,126,10,1,3}, extracts Joseph ring parameters (10,1,3) from the end of the encryption information according to an encryption communication rule agreed with the mobile phone, and obtains a composite number sequence {84,124,108,111,113,101,41,113,102,126 }.

S818: the tablet generates a josephson ring sequence from the josephson ring parameters.

Based on josephson ring parameters (10,1,3), the tablet can generate a josephson ring sequence, {4,7,10,3,8,2,9,6,1,5 }.

S820: and the tablet personal computer analyzes the synthesized number sequence according to the Joseph ring number sequence to obtain a decimal data number sequence.

After the tablet personal computer obtains the Joseph ring sequence, the synthesized sequence can be analyzed according to the Joseph ring sequence, so that the decimal data sequence is obtained. For example, in the present embodiment, the tablet computer determines that the composition operation used in encryption is an addition operation according to the encryption communication rule agreed with the mobile phone, so the tablet computer needs to perform a subtraction operation when analyzing the composition data. And the tablet personal computer subtracts the nth data in the Joseph ring number array from the nth data in the synthesized number array, and uses the calculated difference value as the nth data in the decimal data number array.

When the Joseph ring number is {4,7,10,3,8,2,9,6,1,5}, the synthesized number is {84,124,108,111,113,101,41,113,102,126}, the decimal data obtained by the tablet computer is {80,117,98,108,105,99,32,107,101,121 }.

S822: and the tablet computer determines original information corresponding to the decimal data array according to the ASCII table.

Subsequently, the tablet computer determines the meaning represented by the decimal data sequence {80,117,98,108,105,99,32,107,101,121} from the ASCII table query, and determines the original information as the character string "Public key".

In the information encryption and decryption scheme provided by this embodiment, the joseph ring number array is used as the encryption matrix for encrypting the decimal data number array corresponding to the original information, so that the decryption difficulty of the encrypted information is improved, and the problem of reducing the information security due to the repeated use of the same joseph ring encryption communication is avoided based on the variability of the joseph ring parameters.

The present embodiment will be described with respect to the terminal in the foregoing embodiment, but before describing the structure of the terminal, a computer-readable storage medium is provided:

the computer-readable storage medium stores one or more computer programs that can be read, compiled, or executed by the memory, wherein the computer programs include at least one of an information encryption program and an information decryption program, the information encryption program being executable by the processor to implement the information encryption method provided in the first or third embodiment, and the information decryption program being executable by the processor to implement the information decryption method provided in the second or third embodiment.

It should be understood that, in some examples of the embodiment, the computer-readable storage medium stores therein both the information encryption program and the information decryption program, because in most cases, the information encryption side also needs to be used as the information decryption side, and the information decryption side also has the possibility of being used as the information encryption side.

Meanwhile, the present embodiment further provides a terminal, please refer to fig. 9: the terminal 90 includes a processor 91, a memory 92, and a communication bus 93 for connecting the processor 91 and the memory 92, wherein the memory 92 may be the computer readable storage medium storing the information encryption program and/or the information decryption program. The processor 91 may read the information encryption program stored in the memory 92, compile and execute the information encryption method provided in the foregoing first or third embodiment:

the processor 91 acquires original information to be encrypted, acquires a decimal data number sequence corresponding to the original information, and determines a data number in the decimal data number sequence; subsequently, the processor 91 sets josephson ring parameters (N, K, M) according to the number of data, and generates a josephson ring number sequence containing N decimal data according to the josephson ring parameters, where the value of N is the same as the number of data in the decimal data number sequence; then, the processor 91 synthesizes the decimal data sequence and the joseph ring sequence to obtain a synthesized sequence comprising N decimal data, wherein the nth data in the synthesized sequence is obtained by synthesizing the nth data in the joseph ring sequence and the nth data in the decimal data sequence; finally, the processor 91 performs a second synthesis of the synthesized sequence and the joseph ring parameters to obtain encrypted information.

In one example of the present embodiment, the processor 91 converts the original information into a decimal data array according to an ASCII table.

In an example of the present embodiment, the processor 91 performs one of four arithmetic operations on the nth data in the josephson ring sequence and the nth data in the decimal data sequence to obtain the nth data in the synthesized sequence.

It will be appreciated that the processor 91 may insert the three data in the josephson ring parameters into the synthesized sequence of numbers to obtain a twice synthesized sequence of numbers containing N +3 decimal data.

In other cases, the processor 91 may read the information decryption program stored in the memory 92, compile and execute the information decryption method provided in the foregoing second or third embodiment:

the processor 91 acquires encrypted information to be decrypted, and then disassembles the encrypted information to obtain josephson ring parameters (N, K, M) and a synthesized number sequence, wherein the synthesized number sequence comprises N decimal data; subsequently, the processor 91 generates a josephson ring number sequence containing N decimal data according to the josephson ring parameters, and disassembles the synthesized number sequence according to the josephson ring number sequence to obtain a decimal data number sequence containing N decimal data, wherein the nth data in the decimal data number sequence is obtained according to the nth data in the josephson ring number sequence and the nth data in the synthesized number sequence; finally, the processor 91 converts the decimal data sequence into the original information.

Optionally, the processor 91 extracts the first three bits of data in the encrypted information as N, K, M in the joseph ring parameters;

alternatively, the processor 91 may further extract the last three bits of data in the encrypted information as N, K, and M in the joseph ring parameter, respectively.

The terminal and the computer readable storage medium provided by the embodiment of the invention apply the Joseph ring to generate the Joseph ring number sequence, so that each data in the decimal data number sequence obtained by converting the original information is processed differently, thereby enhancing the decoding difficulty after the ciphertext is intercepted. Moreover, because the Joseph ring parameters are variable, even if the data number in the decimal data number sequence obtained by converting the original information is not changed, different Joseph ring number sequences can be obtained, so that the key matrix has diversification, and the information security is enhanced.
