Embodiment Construction
[0038] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, only a part of the embodiments of the present invention, not all the embodiments, and are not intended to limit the present invention.
[0040] The embodiment of the present invention provides a digital signature verification method, which can be applied to a system including a client and a server, wherein the client generates a request carrying a digital signature according to the client white-box algorithm sent by the server Information, the white box algorithm of the client is generated by the server using the preset encryption algorithm and obfuscation strategy according to the client ID, the digital signa...

Embodiments of the present invention provide a digital signature verification method, system, device, and computer-readable storage medium, which relate to the communication field. Among them, the client generates request information carrying a digital signature according to the client white box algorithm sent by the server. The client white box algorithm is generated by the server using a preset encryption algorithm and obfuscation strategy based on the client ID. The signature is the verification information generated by the white-box algorithm of the client. The client sends the request information to the server; and the server uses the first password corresponding to the client ID to Key to verify the request information to determine whether the request information is legal. Therefore, in the case that the server does not need to store a large amount of data, the verification efficiency is guaranteed; the client-side white-box algorithm is used without any key plaintext on the client side, ensuring key security.
Description
technical field [0001] The present invention relates to the technical field of the Internet, in particular to a digital signature verification method, system, device and computer-readable storage medium. Background technique [0002] At present, digital signatures are widely used in the technical field of communication of mobile terminals, so as to realize identity verification of both communication parties. [0003] In the prior art, most digital signatures are implemented using public key algorithms, using private key signatures and public key verification methods, that is, the client adds data encrypted with the private key after the sent data as a digital signature , after sending it to the server, so that the server can use the public key to decrypt the received digital signature to verify the authenticity of the digital signature. [0004] However, due to the particularity of mobile terminal use scenarios and open-source operating systems, all keys stored in the devic...
