Problems solved by technology

However, due to the uncertainty of the size of the certificate message, it is usually difficult to determine the size of the buffer. For example, if the size of the buffer is determined to be 1K, the certificate message is likely to be sent multiple times, which will also cause the TLS handshake process to take up The time is relatively long, which greatly reduces the connection speed of TLS

Abstract

The present invention provides a message sending and receiving method, device and system. The message sending method comprises: sending a client handshake message to a server, the client handshake message carrying identification of a server certificate cached by the client; receiving a server handshake message sent by the server, when the server determines that the identification of the server certificate cached by the client comprises identification of a certificate to be used by the server, the server handshake message carrying the identification of the certificate to be used by the server; searching the server certificate cached by the client for a server certificate corresponding to the identification of the certificate to be used by the server; and encrypting, through a public key in the found server certificate, a client key exchange message to be sent, and sending the encrypted client key exchange message to the server. By means of the present invention, the data amount in a TLS handshaking process can be reduced, and the time occupied by the TLS handshaking process is shortened, thereby improving the speed of TLS connection.

Description

technical field [0001] The present invention relates to communication technology, in particular to a message sending and receiving method, device and system. Background technique [0002] The Transport Layer Security (TLS for short) protocol is a widely used identity authentication and secure transmission protocol. [0003] In TLS, the security of authentication depends on the security of the server's private key and the security of the certificate itself. It should be noted that the security of authentication is not based on the confidentiality of certificates. A certificate is an object that can be disclosed, as long as the integrity of the certificate is guaranteed. The integrity of the certificate can be guaranteed by digitally signing the certificate through the certificate authority (Certificate Authority; hereinafter referred to as: CA) center. When verifying the integrity of a server's certificate, any entity can use the CA certificate for verification. [0004] ...
