The embodiment of the invention relates to the technical field of network security, and particularly relates to a digital signature method and device based on a national secret algorithm. The method comprises the following steps: a terminal receives a digital signature request, wherein the digital signature request comprises to-be-signed data; the terminal sends a signer feature data ZA request to a server, so that the server calculates a ZA value; the terminal receives the ZA value fed back by the server, and calculates an abstract of the to-be-signed data according to the ZA value and the to-be-signed data; and the terminal sends the abstract of the to-be-signed data to the server, so that the server calculate signature of the abstract of the to-be-signed data according to the national secret algorithm. By adoption of the digital signature method and device provided by the embodiment of the invention, network resources are saved, and the security and efficiency of digital signature are improved.
Description
technical field [0001] The invention relates to the technical field of network security, in particular to a digital signature method and device based on a national secret algorithm. Background technique [0002] A digital signature is some data attached to a data unit, or a cryptographic transformation of a data unit. This data or transformation allows the recipient of the data unit to confirm the origin and integrity of the data unit and protect the data from forgery by others. A digital signature generated by the sender of the information that others cannot forge is a digital signature. This digital string is also an effective proof of the authenticity of the information sent by the sender of the information. [0003] Digital signature is the application of asymmetric key encryption technology and digital abstract technology. Cryptographic algorithms are mathematical functions used for encryption and decryption, and are the basis of cryptographic protocols. Current crypt...
