Problems solved by technology

[0004] During the research and practice of this method, the inventor of the present invention found that: in the prior art, regardless of whether the client communicates with the server for the first time, Every time the client and the server perform a TLS handshake, the server must send the complete server certificate chain to the client. Therefore, there is a problem of high transmission overhead in the message transmission method when the TLS handshake is performed in the prior art method

Embodiment Construction

[0023] An embodiment of the present invention provides a message transmission method capable of reducing transmission overhead. Embodiments of the present invention also provide corresponding network devices and network systems. Each will be described in detail below.

[0024] figure 1 It is a flowchart of a message transmission method according to Embodiment 1 of the present invention, which mainly includes steps:

[0025] Step 101. Receive a first message, which carries an authentication string value generated according to the certificate chain;

[0026] Step 102. When it is determined that the authentication string value in the first message is the authentication string value corresponding to the adopted certificate chain, send a second message, and the second message indicates that the authentication string value in the first message is adopted. The certificate chain corresponding to the string value.

[0027] Wherein, the received first message includes a client disco...

Abstract

The embodiment of the invention discloses a message transmission method, network device and network system. The message transmission method comprises: receiving a first message which carries approved string value produced according to a certificate chain; sending a second message, when the approved string value in the first message is the adopted corresponding approved string value. The second message shows that the approved string value in the first message is the corresponding certificate chain. Correspondingly, the embodiment of the invention also provides a network device and network system. The technique proposal provided by the embodiment of the invention can reduce the cost of the transmission process.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a message transmission method, a network device and a network system. Background technique [0002] Secure Sockets Layer (SSL, Secure Sockets Layer) protocol and Transport Layer Security (TLS, TransportLayer Security) protocol are a communication protocol that provides security and confidentiality on the Internet, and provide secure and confidential services for data transmission such as email transmission and online fax. This document uses the TLS protocol as an example for illustration. The TLS protocol uses key algorithms to provide services such as identity authentication and communication confidentiality between endpoints on the Internet, and its application basis is generally Public Key Infrastructure (PKI, Public Key Infrastructure). [0003] During the handshake process of the TLS protocol, when the client connects to the server for the first time, it will send a cl...
