Data signature method, system and device

Abstract

The invention discloses a data signature method. Firstly, an identity authentication file, a to-be-signed message and a public key and a private key which are generated by utilizing an SM2 algorithm are acquired; the identity authentication file and the public key are operated through an SM3 algorithm to obtain a first hash value, the first hash value and the to-be-signed message are operated to obtain a second hash value, and finally SM2 signature is conducted on the to-be-signed message according to the second hash value and the private key so that signature encryption can be conducted on the to-be-signed message. Visibly, the signature encryption of the to-be-signed message is realized by adopting multiple operations of the SM2 algorithm and the SM3 algorithm, and the solving difficultyof the algorithm is relatively high, so that the data encryption security is improved. The invention further discloses a data signature system and device which have the same beneficial effects as thedata signature method.

Description

technical field [0001] The invention relates to the field of data security, in particular to a data signature method, system and device. Background technique [0002] Due to the large amount of data and personal information transmitted on the Internet, it is very important to ensure the security of information during communication. In the prior art, in order to ensure the information security during the communication process, various encryption algorithms are usually used to encrypt the information during the communication process, so as to prevent the data from being illegally stolen and monitored. At present, the more commonly used encryption algorithm is the RSA algorithm (proposed by Ron Rivest, Adi Shamir, and Leonard Adleman together, and RSA is composed of the initial letters of the three surnames). However, the RSA algorithm is less difficult to solve, resulting in data encryption security. Sex is lower. [0003] Therefore, how to provide a solution to the above te...
