Embodiment

[0045] Assuming that the request parameters participating in the parameter signature calculation are "a1", "a2", and "a3", and their values ​​are "b1", "b2", and "b3" respectively, the calculation method of the parameter signature is as follows:

[0046] Step 1: Format the request parameters as "a1=b1", "a2=b2", "a3=b3" to form a matching relationship pair.

[0047]Step 2: Arrange the matched and formatted parameter key-value pairs in lexicographical ascending order, and splicing them together, that is, "a1=b1a2=b2a3=b3". Here, the ascending order of the dictionary can effectively solve the problem of matching. Sequence problem.

[0048] Step 3: Add the key SESSION_SECRET parameter value obtained by the user at the beginning of the application at the end of the concatenated string;

[0049] Step 4: Perform MD5 operation on the above string, and the MD5 value obtained is the value generated by the signature algorithm.

Abstract

The invention provides a signature algorithm for server validation. The signature algorithm includes the following achievement steps: when a WEB front-end server communicates with a background server, a signature is added to a request parameter, character strings are formed through a specific combination of the parameters and are spliced, the finally obtained character strings are subjected to MD5 signature to serve as a communication passing parameter; the signature is recomputed when a server end receives a request, whether the request parameter is consistent with the passing parameter is judged, and if not, it is indicated that the call request is forged or tampered with. Compared with the prior art, the signature algorithm for server validation guarantees safety in the passing process through multi-hierarchy encryption, and guarantees accuracy in the receiving process by using a matched algorithm of the signature algorithm on the server.

Description

technical field [0001] The present invention relates to the field of computer technology, and specifically relates to a signature algorithm for verifying with the server by setting the parameter content when HTTP sends the request, and performing effective matching verification on the server to achieve the effect of signature verification. Background technique [0002] In the existing technology, verification is required every time the program calls the server, and signature verification through server secure communication has become the focus of people's increasing attention. Generally, the following problems exist in the signing process: [0003] First, when sending based on HTTP POST or HTTP GET requests, how to set the request parameters more effectively and less easily to be cracked is the biggest problem that needs to be solved. Ensuring the security of the communication process is a big issue. problem. [0004] Second, how to prevent others from obtaining your user I...
