Security authentication method, device and system based on security transport layer protocol

Abstract

The embodiment of the invention discloses a TLS-based security authentication method, related equipment and a communication system. A method for security authentication based on the TLS protocol, comprising: a client sends a client initialization handshake message to a server, the client initialization handshake message carries N algorithm set identifiers, and M algorithm set identifiers among the N algorithm set identifiers The algorithm set corresponding to each algorithm set identifier in includes the SM2 algorithm; receiving the server initialization handshake message sent by the server, the server initialization handshake message carries the first algorithm set identifier, and the first algorithm set identifier is one of the M algorithm set identifiers One of them; performing security authentication with the server based on the first algorithm set corresponding to the first algorithm set identifier. The scheme of the embodiment of the present invention provides a mechanism capable of using the SM2 algorithm for data transmission, which is beneficial to give play to the advantages of the SM2 algorithm in terms of security, and improve the security and performance of security authentication and data transmission.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a security authentication method, device and system based on a security transport layer protocol. Background technique [0002] Currently, the Transport Layer Security (TLS) protocol is the most widely used security protocol in network transmission. The TLS protocol is an international standard, and the TLS protocol uses a large number of internationally used related algorithms. [0003] The SM2 algorithm is an asymmetric encryption algorithm issued by the National Standard Cryptography Bureau of China, and is designated by the Ministry of Industry and Information Technology to replace the RSA algorithm. Among them, the SM2 algorithm adopts the principle of elliptic curve, its key is relatively shorter, its security is relatively higher, and its performance is relatively higher. Among them, the SM2 algorithm includes: SM2 public key encryption algorithm, SM2 signature al...
