Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For a better understanding of the embodiments of the present invention, the technical terms related to the embodiments of the present invention will be explained first:
Json: json (JavaScript Object Notation, JS object numbered musical notation) is a lightweight data exchange format. It stores and presents data in a text format that is completely independent of the programming language, based on a subset of ECMAScript (js specification formulated by the european computer institute). The compact and clear hierarchical structure makes Json an ideal data exchange language. Is easy to read and write by people, is easy to analyze and generate by machines, and effectively improves the network transmission efficiency.
SM4 encryption algorithm: SM4.0 (original name SMs 4.0) is a block cipher standard adopted by the government of the people's republic of China, issued by the national cipher administration on day 21, 3, 2012. The relevant standard is "GM/T0002-2012" SM4 block cipher algorithm (original SMS4 block cipher algorithm) ".
In a commercial cryptosystem, SM4 is mainly used for data encryption, an algorithm of the SM4 discloses that the packet length and the key length are 128 bits, the encryption algorithm and the key expansion algorithm both adopt a 32-round nonlinear iteration structure, and an S box is fixed 8-bit input and 8-bit output.
The instruction length in SM4.0 is raised to a level greater than 64K (i.e., 64 x 1024), which is 128 times the SM 3.0 specification (rendering instruction length allowed to be greater than 512).
The inventors have found that there may be two situations when parameters are passed into a function: (1) When the parameters to be transmitted do not meet the format check requirement of the function and the parameters are required to be transmitted; (2) At mian function entry, the incoming Json will automatically be converted into a string array, resulting in erroneous parameter readings.
For the first case, the method of replacing with special symbols is mostly used, and this case finds that replacing one special character with another one makes parameter transfer very complicated and there is an unpredictable risk. The Json character string transmitted by the main function inlet is automatically converted into a character string array, and the Json character string can be processed as the character string array without any solution; if Json string elements are numerous, the main function can be quite cumbersome to handle for the joining.
Therefore, an embodiment of the present invention provides a complex format parameter transmission method for simply, quickly and safely transmitting complex format parameters, as shown in fig. 1, where the method includes:
Step 101: determining whether the incoming parameters are complex format parameters;
Step 102: when the input parameters are parameters in a complex format, the SM encryption algorithm is utilized to convert the input parameters into encryption parameters;
step 103: and after the encryption parameters are transferred to the function, decrypting the encryption parameters read by the function by using an SM encryption algorithm to obtain decrypted complex format parameters.
As can be seen from the flow shown in fig. 1, in the embodiment of the present invention, whether the incoming parameters are complex format parameters is determined; when the input parameters are parameters in a complex format, the SM encryption algorithm is utilized to convert the input parameters into encryption parameters; and after the encryption parameters are transferred to the function, decrypting the encryption parameters read by the function by using an SM encryption algorithm to obtain decrypted complex format parameters. By encrypting the complex format parameters by using the SM encryption algorithm and decrypting after the complex format parameters are transmitted into the function, the function is prevented from checking the format of the complex format parameters when the complex format parameters are transmitted, and compared with the method adopting special symbol replacement in the prior art, the method is simple and quick, the unpredictable risk caused by the fact that characters cannot be determined is avoided, and the method is safer.
In implementation, first, it is determined whether the incoming parameters are complex format parameters, and the implementation process, as shown in fig. 2, includes:
Step 201: acquiring function information and incoming parameter information of parameter transfer;
step 202: and when the function is main function and the input parameter is Json character string according to the function information and the input parameter information of the parameter transfer, determining that the input parameter is a complex format parameter.
In a specific embodiment, the implementation method for determining whether the incoming parameters are complex format parameters, as shown in fig. 3, further includes, based on fig. 2:
Step 301: when the function is determined not to be a main function or the input parameter is determined not to be a Json character string, a format check result of the function on the input parameter is obtained;
Step 302: if the format check result is that the special character exists, determining that the input parameter is a complex format parameter.
After determining that the input parameters are parameters in a complex format, the input parameters are converted into encryption parameters by using an SM encryption algorithm. The specific implementation process, as shown in fig. 4, includes:
step 401: determining a part which does not meet the format requirement in the input parameters according to the format check result;
step 402: converting the part which does not meet the format requirement in the input parameters into an encryption character string by using an SM encryption algorithm;
Step 403: and replacing the part which does not meet the format requirement in the input parameters by using the encryption character string to obtain the encryption parameters.
In the specific embodiment, the problem of illegal parameters can be thoroughly solved by encrypting part of the content which does not accord with the parameter format into a 16-system character string through an SM4 encryption algorithm.
And after the SM encryption algorithm is utilized to convert the input parameters into the encryption parameters, the encryption parameters are transferred to the function. After the function is read, the encryption parameters read by the function are decrypted by using an SM encryption algorithm, and the decrypted complex format parameters are obtained. And (3) after decrypting the read encrypted character string, re-splicing the read encrypted character string with the rest of the parameters to obtain original parameter content, and transmitting the original parameter content to a subsequent program.
In the specific embodiment of the invention, an encryption algorithm is used for illegal parameters to convert illegal parts into character strings of pure letter data, and then the character strings are combined into legal parameters. The parameter content is not changed, but format checking when the function is participating (the parameter is imported) or excessive conversion of main function participating to Json format is avoided. Thereby solving the problem of illegally entering the ginseng at one time and quickly. And the encryption is carried out on the ginseng, so that the confidentiality is improved. The related work of the test is realized, and no bug is generated after the test is basically finished.
A specific example is given below to illustrate how the embodiment of the present invention performs complex format parameter delivery. The method is applied to main functions to input a large Json character string, and spaces exist in the large Json character string, so that the main functions can be used for inputting a plurality of parameters, and the subsequent program processing errors are caused.
The following are provided:
original entry of "name": "haidi", "id": "888", "remarks": "this is an sample" }
The intention is to take only one parameter and directly analyze it by Json
{“name”:”haidi”,”id”:”888”,”remarks”:”this is an example.”}
The actual input through the main function is divided by space.
First parameter: { "name": "haidi", "id": "888", "remarks": "this
The second parameter:
is
Third parameter:
an
fourth parameter:
example.”}
If the complex format parameter transmission method provided by the above embodiment is used for encryption, then:
original entry of "name": "haidi", "id": "888", "remarks": "this is an sample" }
After passing through the encryption process, it is similar to: ciphertext such as 4r5fse232dd8hfd is decrypted after the ciphertext is transmitted, and then the result is half-time according to Json analysis.
The implementation of the above specific application is only an example, and the rest of the embodiments are not described in detail.
Based on the same inventive concept, the embodiment of the present invention further provides a complex format parameter transmission device, and because the principle of the problem solved by the complex format parameter transmission device is similar to that of the complex format parameter transmission method, the implementation of the complex format parameter transmission device can refer to the implementation of the complex format parameter transmission method, and the repetition is omitted, and the specific structure is shown in fig. 5:

acquiring function information and incoming parameter information of parameter transfer;
And determining that the input parameter is a complex format parameter when the function is main function and the input parameter is Json character string according to the function information and the input parameter information of parameter transfer.
