Abstract
The invention relates to a data transfer encryption method for mobile communication, belonging to the technical field of data communication and aiming at improving the safety of data transfer. The method comprises the following specific steps: a mobile terminal encrypts a text to be sent into a cipher text by using an AES (Advanced Encryption Standard) algorithm and sends the cipher text to a server; the server deciphers the received cipher text by using the AES algorithm and processes the deciphered text; the server generates a text to be returned after processing the received text, encrypts the text to be returned into a cipher text by using the AES algorithm and sends the cipher text to the mobile terminal; and the mobile terminal deciphers the received cipher text into a plain text by using the AES algorithm and outputs the plain text to a display screen to display. Through the method provided by the invention, the safety of data transfer can be improved.
Description
Technical field
The present invention relates to data communication technology, particularly relate to a kind of technology of transfer of data encryption method of mobile communication.
Background technology
Along with the fast development of mobile communication technology, the wireless terminal device among the mobile network is used increasingly extensive, based on the also develop rapidly of types of applications of mobile device.Along with the requirement that the networking of data is handled is more and more higher, also growing by the demand of pocket wireless mobile apparatus access internet networks such as mobile phone, PDA.
At present, the data of transmitting between mobile device and the server all adopt the XML form to define, and all business datums all are to exist in character string forms, and it is relatively poor that these data are uploaded fail safe sowing time at public network, be easy to be intercepted, thereby influence user's interests by the hacker.
Summary of the invention
At the defective that exists in the above-mentioned prior art, technical problem to be solved by this invention provides the transfer of data encryption method of the high mobile communication of a kind of transmission security.
In order to solve the problems of the technologies described above, the transfer of data encryption method of a kind of mobile communication provided by the present invention is characterized in that concrete steps are as follows:
Before portable terminal is initiated communication request, adopt aes algorithm that the text encryption to be sent of XML form is become byte arrays earlier, send to server after again this byte arrays being converted to the character string ciphertext of 16 systems;
After server is received the character string ciphertext of portable terminal transmission, earlier convert the character string ciphertext of receiving to byte arrays, adopt aes algorithm to this byte arrays deciphering again, and then adopt the reception text of the byte arrays structure XML form after this time deciphering, and then the butt joint message in-coming is originally handled;
Promptly generate the returned text for the treatment of of XML form after server butt joint message in-coming originally disposes, and adopt aes algorithm will treat that returned text is encrypted to byte arrays, and then send to portable terminal after this byte arrays being converted to the character string ciphertext of 16 systems;
After portable terminal is received the character string ciphertext that server returns, earlier convert the character string ciphertext to byte arrays, adopt aes algorithm to this byte arrays deciphering again, and then adopt the returned text of the byte arrays structure XML form after this time deciphering, and then export returned text to display screen and show.
The transfer of data encryption method of mobile communication provided by the invention; adopt aes algorithm that the transmission data between portable terminal and the server are encrypted; making the transmission transformation of data between portable terminal and the server is ciphertext; realized information hiding; even if the hacker has intercepted ciphertext; also can't learn content expressly, thereby play the effect of the safety of protection information, can improve safety of data transmission.
Description of drawings
Fig. 1 is the fundamental diagram of transfer of data encryption method of the mobile communication of the embodiment of the invention.
Embodiment
Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.
As shown in Figure 1, the transfer of data encryption method of a kind of mobile communication that the embodiment of the invention provided is characterized in that, concrete steps are as follows:
Before portable terminal is initiated communication request, adopt aes algorithm that the text encryption to be sent of XML form is become byte arrays earlier, send to server after again this byte arrays being converted to the character string ciphertext of 16 systems;
After server is received the character string ciphertext of portable terminal transmission, earlier convert the character string ciphertext of receiving to byte arrays, adopt aes algorithm to this byte arrays deciphering again, and then convert the byte arrays after this time deciphering to the character string text, thereby construct the reception text of XML form, and then the butt joint message in-coming is handled originally;
Promptly generate the returned text for the treatment of of XML form after server butt joint message in-coming originally disposes, and adopt aes algorithm will treat that returned text is encrypted to byte arrays, and then send to portable terminal after this byte arrays being converted to the character string ciphertext of 16 systems;
After portable terminal is received the character string ciphertext that server returns, earlier convert the character string ciphertext to byte arrays, adopt aes algorithm to this byte arrays deciphering again, and then convert the byte data after this time deciphering to the character string text, thereby construct the returned text of XML form, and then export returned text to the display screen demonstration.
The described aes algorithm of the embodiment of the invention is a prior art, aes algorithm is based on the algorithm of arranging and replacing, arrangement is that the data sequence is arranged again, displacement is by setting rule data cell to be replaced with another data cell, AES uses several diverse ways to carry out and arranges and in-place computation, it is an iteration, the password of symmetric key grouping, can use 128,192 and 256 key, and with 128 (16 byte) block encryption and data decryptions, symmetric key cipher is used identical secret key encryption and data decryption, the figure place of the enciphered data of returning by block cipher is identical with the input data, iterative cryptographic uses a loop structure, repeats displacement and replace the input data in this circulation.
