Transport layer security (TLS) channel constructing method based on cryptographic algorithm

Abstract

The invention relates to the technical field of network safety and provides a transport layer security (TLS) channel constructing method based on a cryptographic algorithm. The TLS channel constructing method includes steps that: a server side launches a request and a client side respond to a hello message, or the client side launches the hello message; the server side responds to the hello message of the server side; the server side transmits an SM2 certificate to the server side and then transmits a hello completing message; the client side receives the hello completing message and then transmits a secret key exchange message; the client side transmits a cipher suite change message and a finishing message, and the server side transmits the cipher suite change message and the finishing message after receiving the finishing message of the client side; and the server side and the client side perform data safe transmission according to the agreed safety parameters after receiving the finishing messages of each other and passing verification. According to the TLS channel constructing method, the cryptographic algorithm is blended into a TLS protocol to perform safety communication, the signature speed is obviously superior to that of a remote signaling alarm (RSA) algorithm by aid of short secret key length, and the TLS channel constructing method is a data safety method with the 2048-bit safety level of the RSA algorithm.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method for establishing a TLS channel based on a national secret algorithm. Background technique [0002] Cryptographic algorithms are mathematical functions used for encryption and decryption, and are the basis of cryptographic protocols. Current cryptographic algorithms mainly include sequence ciphers, block ciphers, public key ciphers, hash functions, etc., which are mainly used to ensure information security and provide authentication , integrity, non-repudiation and other services. Commercial encryption refers to the encryption technology and encryption products used for encryption protection or security authentication of non-classified information, and is mainly used in general industrial and commercial fields that do not involve state secrets. Due to the emergence of many different cryptographic algorithms based on different encryption and decryption ideas in t...
