Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For a better understanding of the embodiments of the present invention, the terms of art to which the embodiments of the present invention relate will first be explained:
json: json (JavaScript Object Notation) is a lightweight data exchange format. It stores and represents data in a text format that is completely independent of the programming language, based on a subset of ECMAScript (js specification set by the european computer association). The compact and clear hierarchy makes Json an ideal data exchange language. The network transmission method 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 SMs4.0) is a block cipher standard adopted by the government of the people's republic of china and issued by the national cipher authority on day 3/21 of 2012. The relevant standard is "GM/T0002-.
In a commercial cryptosystem, the SM4 is mainly used for data encryption, the algorithm is public, the packet length and the key length are both 128 bits, both the encryption algorithm and the key expansion algorithm adopt 32-round nonlinear iterative structures, and the S-box is a fixed 8-bit input 8-bit output.
The instruction length in SM4.0 is raised to a level greater than 64K (i.e., 64 × 1024), which is 128 times that of the SM 3.0 specification (rendering instruction length allowed to be greater than 512).
The inventors have found that when parameters are passed into a function, there may be two cases: (1) when the parameters which need to be transmitted do not meet the format checking requirement of the function and the parameters need to be transmitted; (2) at the entrance of the mian function, the incoming Json will automatically convert into a string array, resulting in the parameter reading error.
In the first case, a method of replacing the first character with a special symbol is used, and in this case, the fact that one character is replaced with another character makes parameter passing very complicated and risks being unpredictable. The Json character string introduced by the main function inlet is automatically converted into a character string array, and the Json character string is not provided with any solution and can only be processed as the character string array; the main function can also be quite cumbersome to process for enlisting if there are a sufficient number of Json string elements.
Therefore, an embodiment of the present invention provides a complex format parameter delivery method, which is used to simply, quickly, and safely deliver complex format parameters, as shown in fig. 1, and the method includes:
step 101: determining whether the incoming parameter is a complex format parameter;
step 102: when the incoming parameters are complex format parameters, the incoming parameters are converted into encryption parameters by using an SM encryption algorithm;
step 103: and after the encryption parameters are transferred to the function, the encryption parameters read by the function are decrypted by using an SM encryption algorithm to obtain the decrypted complex format parameters.
As can be known from the flow shown in fig. 1, in the embodiment of the present invention, whether the incoming parameter is a complex format parameter is determined; when the incoming parameters are complex format parameters, the incoming parameters are converted into encryption parameters by using an SM encryption algorithm; and after the encryption parameters are transferred to the function, the encryption parameters read by the function are decrypted by using an SM encryption algorithm to obtain the decrypted complex format parameters. The SM encryption algorithm is used for encrypting the complex format parameters and decrypting the complex format parameters after the complex format parameters are transmitted into the function, so that the format check of the function on the complex format parameters is avoided when the complex format parameters are transmitted.
In the implementation, it is first determined whether the incoming parameter is a complex format parameter, 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 according to the function information and the incoming parameter information transmitted by the parameters, when the function is determined to be a main function and the incoming parameters are Json character strings, determining the incoming parameters to be complex format parameters.
In an embodiment, the implementation method for determining whether an incoming parameter is a complex format parameter, as shown in fig. 3, on the basis of fig. 2, further includes:
step 301: when the function is determined not to be a main function or the incoming parameter is determined not to be a Json character string, acquiring a format check result of the function on the incoming parameter;
step 302: if the format checking result shows that the special characters exist, the transmitted parameters are determined to be complex format parameters.
And after determining that the incoming parameters are complex format parameters, converting the incoming parameters into encryption parameters by using an SM encryption algorithm. The specific implementation process, as shown in fig. 4, includes:
step 401: determining the part which does not meet the format requirement in the incoming parameters according to the format checking 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 incoming parameters by using the encryption character string to obtain the encryption parameters.
In the specific embodiment, the problem of illegal parameters can be completely solved by encrypting the partial content which does not conform to the parameter format into a 16-system character string through an SM4 encryption algorithm.
After the incoming parameters are converted into encryption parameters by using the SM encryption algorithm, the encryption parameters are transferred to the function. And after the function is read, decrypting the encryption parameter read by the function by using an SM encryption algorithm to obtain the decrypted complex format parameter. After the read encrypted character string is decrypted and spliced with the rest of the parameters again, the original parameter content is obtained and transmitted to a subsequent program.
In the specific embodiment of the invention, for illegal parameters, an encryption algorithm is used to convert the illegal parts into character strings of pure alphabetic data, and then the character strings are combined into legal parameters. The parameter content is not changed, but excessive conversion of the main function join to the Json format or format check when the function joins (incoming parameters) is avoided. Therefore, the problem of illegal participation is solved at one time and quickly. And the access participants are encrypted, so that the confidentiality is improved. And the related work of the test is basically realized, and the production execution is free from bug after the test.
A specific example is given below to illustrate how embodiments of the present invention perform complex format parameter passing. The example is applied to the main function, a large Json character string is introduced, and a blank space exists in the character string, so that the main function considers that a plurality of parameters are introduced, and the subsequent program processing is wrong.
The following were used:
original references { "name": haidi "," id ": 888", "remarks": this is an example "}
This means that only one parameter is taken and directly analyzed by Json
{“name”:”haidi”,”id”:”888”,”remarks”:”this is an example.”}
What actually comes in through the main function will be partitioned by spaces.
The first parameter is: { "name": haidi "," id ": 888", "remarks": this
The second parameter is:
is
the third parameter:
an
the fourth parameter:
example.”}
if the complex format parameter transmission method provided by the above embodiment is used for encryption:
original references { "name": haidi "," id ": 888", "remarks": this is an example "}
After the encryption processing, similar to: 4r5fse232dd8hfd74, after the ciphertext is transmitted, the ciphertext is decrypted and analyzed according to Json, so that the result is twice with half the effort.
The implementation of the above specific application is only an example, and the rest of the embodiments are not described in detail.

when the function is determined not to be a main function or the incoming parameter is determined not to be a Json character string, acquiring a format check result of the function on the incoming parameter;
