Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Fig. 1 is an overall implementation flowchart of data transmission in an embodiment of the present invention, as shown in the figure, the steps of the data transmission method are as follows:

S1: Build a front-end page, the front-end page has a cross-platform feature and is used to interact with the back-end system.

The construction of the front-end page needs to download the React installation package. First, use the web page source code of React, and its structure is as follows:

<! DOCTYPEhtml><html><head><scriptsrc="../build/react.js"></script><scriptsrc="../build/react-dom.js"></script><scriptsrc=" ../build/browser.min.js"></script></head><body><divid="example"></div><scriptt type="text/babel">//**User code **</script></body></html>.

The type attribute of the last <script> tag is text/babel. This is because React's unique JSX syntax is not compatible with JavaScript. Wherever JSX is used, type="text/babel" must be added. Secondly, the above code shares three libraries: react.js, react-dom.js and Browser.js, which must be loaded first. Among them, react.js is the core library of React, react-dom.js provides functions related to DOM, and the function of Browser.js is to convert JSX syntax into JavaScript syntax. This step is very time-consuming. When it is actually launched, it should be Putting it on the server is done.

Secondly, the js files in the src subdirectory are syntax converted, and all the transcoded files are placed in the build subdirectory $babelsrc--out-dirbuild.

Finally, rendering is converted into html nodes to facilitate dom manipulation: ReactDOM.render is the most basic method of React, which is used to convert templates into HTML language and insert specified DOM nodes. Here is an example of inserting hello world:

ReactDOM. render(<h1>Helloworld!</h1>, document. getElementById('example')).

S2: Deploy a set of encryption and decryption rules supported by all back-end systems, and set up a key generation system in conjunction with the encryption and decryption rules, and the key generation system is used to generate keys and manage keys.

The MAC address filtering here can specify that certain MAC addresses can access the wireless network and others cannot. The "separate key" function can specify a separate key for a single MAC, and this key only has the network card with this MAC address. It can be used, but other network cards cannot be used, which increases a certain degree of security. Open "Wireless Settings" -> "MAC Address Filtering", "Add New Item" on the "MAC Address Filtering" page, the following interface is the interface for filling in parameters:

The "MAC address" parameter we fill in is the MAC address 00-0A-EB-88-65-06 of the TL-WN620G in this example, and the "Type" can choose "Allow"/"Prohibit"/"64-bit key" /"128-bit key"/"152-bit key", 64-bit key is selected in this example. "Allow" and "Prohibit" simply allow or prohibit the passage of a certain MAC address, which is the same as the previous MAC address function, which is not the focus here. The "key" is filled with 10 digits AAAAAAAAAA, there is no "key format selection" here, only "hexadecimal" input is supported. The "Status" selection takes effect. Finally click save, after saving, it will return to the previous interface, where the status of "MAC address filtering function" is "enabled", if it is "closed", the button on the right will change to "enable filtering", click this button to Enable this feature.

S3: Use the key generation system and encryption and decryption rules to generate ciphertext, and pass the ciphertext as a transmission parameter to the front-end page as the data destination.

The transmission of the encrypted data realizes the data exchange between the front-end page and the back-end system by connecting the same table of the same database server. When the front-end page requests the back-end system to process data, the front-end page Inserts a piece of data, and the back-end system selects the data inserted by the front-end page for processing.

S4: Receive the ciphertext sent by the front-end page, and use the key generation system and encryption and decryption rules to decrypt the ciphertext into plaintext.

Judging by the test experiment, if the function between the data interface of the front-end page and the data interface of the back-end system is normal, then the next operation will be smoothly entered.

S10402: If the function of establishing a data transmission connection between the front-end page and the back-end is abnormal, output corresponding error information to the front-end page.

Judging by the test experiment, if the function between the data interface of the front-end page and the data interface of the back-end system is not normal, the system will issue an error report.

Fig. 4 is a flow chart of setting a key system in an embodiment of the present invention, as shown in the figure, the step S2 includes steps S201 to S202:

The key generation system is used to generate keys for encrypting data and decrypting data. The key is used as a parameter to encrypt data to be transmitted into ciphertext, and decrypt data received by the back-end system into plaintext.

Fig. 5 is a flow chart of encrypting and transmitting encrypted data in one embodiment of the present invention, as shown in the figure, the step S3 includes steps S301 to S303:

S301: The front-end page calls the data interface of the back-end system as a data source, and sends a data transmission request to the back-end system.

As a data source, the back-end system invokes the data interface of the back-end system through the front-end page to send a request for data transmission to the back-end system.

S302: According to the request of the front-end page, the back-end system sends a request to the key generation system, and the key generation system generates a key according to the request, and returns the generated key to the back-end system.

The back-end system sends a request to the key generation system to generate a key according to the request of the front-end page, and the key generation system generates a key according to the request of the back-end system, and transmits the key to the back-end system.

S303: After receiving the key, the back-end system uses it as a parameter of the encryption algorithm in the encryption and decryption rules, encrypts the data requested by the front-end page to form a ciphertext, and feeds the ciphertext as a response to the front-end page.

The back-end system uses the key to encrypt the data to be transmitted to form a scrambled ciphertext, and the back-end system rewards the encrypted ciphertext and feeds it back to the front-end page. A key update mechanism is set in the key generation system, and the key is regularly updated by setting an update cycle to reduce the probability of the transmitted ciphertext being brute force cracked;

Fig. 6 is a flow chart of receiving and decrypting data in an embodiment of the present invention, as shown in the figure, the step SS includes steps S401 to S403:

S401: the backend system interacts with the frontend page when receiving data, and establishes a data transmission channel, the frontend page calls the data interface of the backend system, and transmits the ciphertext with the time stamp to the backend system receiving the data middle.

The back-end system, after confirming the correct front-end page, establishes a data transmission channel for data transmission between the front-end page and the back-end system, and the front-end page attaches a timestamp to the encrypted data obtained, and passes the transmission Channel, which transmits time-stamped data to the backend system.

S402: After receiving the ciphertext, the back-end system sends a request to the key generation system to obtain the key, and decrypts the ciphertext received from the front-end page into plaintext data.

After the back-end system successfully receives the ciphertext, it sends a request to the key generation system to obtain the key to obtain the key, which is used to decrypt the encrypted data and obtain readable plaintext. Among them, it is necessary to judge whether the decrypted data is decrypted successfully. And judge whether the time stamp attached to the data is within the allowable error range. The allowable error range of the time stamp is automatically set by personnel. The front-end page and the back-end system are located in the same time zone. After the back-end system attaches the time stamp to the ciphertext Passed to the front-end page, the timestamp format is: minute:second:hour-day-month-year. If the front-end page and the back-end system are located in different time zones, you need to add or subtract the timestamp of the time zone difference to the timestamp generated by the local time to generate a timestamp for attaching to the ciphertext;

Regardless of whether different back-end systems are used as data sources or data destinations, due to the existence of time differences or transmission delays, it is impossible to ensure that the two are completely synchronized when obtaining the key. , the encryption and decryption rules are stipulated as follows: when decrypting, the backend system of the data source and destination is allowed to use the keys of the latest versions for decryption. When any of the keys is decrypted successfully, the decryption is successful.

Fig. 7 is a flow chart of judging whether the time stamp is within the allowable error range in one embodiment of the present invention. As shown in the figure, in step S402, when the back-end system decrypts the ciphertext, when the decryption fails, the destination of the data The end system requests the key generation system to obtain the key again to decrypt the ciphertext. When the number of decryption failures accumulates to a certain number of times, the back-end system feeds back the front-end page decryption failure information; in step S402, the back-end system When decrypting the ciphertext, after the decryption is successful, it is also judged whether the time stamp attached to the ciphertext is within the error tolerance range, and the judging step includes: the step S402 includes steps S40201 to 40204:

S40201: If the time stamp attached to the data is not within the allowable error range, return an error message indicating that the time stamp is wrong.

For the ciphertext transmitted to the backend system, if the data decryption is unsuccessful and no readable plaintext is obtained, the backend system will issue an error prompt and report an error message.

S40202: If the time stamp attached to the data is within the allowable range of error, the back-end system successfully receives the data, and the back-end system feeds back the successful decryption to the front-end page, and the front-end page records the data reception status to realize safe data transmission.

For the ciphertext transmitted to the back-end system, if the decrypted data is successful and readable plaintext is obtained, continue to judge whether the appended timestamp is within the error tolerance range.

If the front-end page and the back-end system are in the same time zone, the format of the timestamp is: minute:second:hour, day-month-year; if the front-end page and the back-end system are in different time zones, the timestamp generated in the local time is required Add or subtract the timestamp of the time zone difference to generate a timestamp for attaching to the ciphertext; according to the range of the set timestamp, if it is judged that the timestamp is not within the allowable range of error, the timestamp will be returned and an error message will be reported. If the attached timestamp is within the allowable error range, the backend system accepts the data successfully.
