Problems solved by technology

[0007] If some old version of the client cannot support the newer algorithm in the certificate, the negotiation will fail, resulting in the client being unable to access the website through HTTPS, poor compatibility of the website, resulting in low communication security

Embodiment Construction

[0063] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0064] SSL / TLS is a secure network transmission protocol, mainly to protect confidential information transmitted on the Internet. The protocol includes two processes: the handshake phase and the data transmission phase.

[0065] The data transmission stage is to use the negotiated symmetric key to encrypt and decrypt the transmitted data, and the digest key to perform digest operation to ensure the privacy and integrity of the data.

[0066] The main purpose of the handshake phase is to confirm the authenticity and validity of the identity of the other party and generate the secret key required for the data transmission phase.

[0067] The SSL handshake process is as follows:

[0068] a. Client item The...

Abstract

Provided are a method and device for loading a digital certificate in SSL or TLS communication. The method comprises: receiving a handshake request message sent by a client based on a secure sockets layer (SSL) or transport layer security (TLS); according to the handshake request message, verifying a key exchange mode and a first signature mode supported by the client; judging whether the key exchange mode and the first signature mode match a currently loaded digital certificate; if not, loading another digital certificate matching the key exchange mode and the first signature mode; and according to the key exchange mode and the first signature mode successfully matching the digital certificate, returning a handshake response message to the client.The embodiments of the present application achieve dynamic loading of a suitable digital certificate in a handshake negotiation process, thereby ensuring successful completion of SSL / TLS handshake negotiation.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a method for loading a digital certificate in SSL / TLS communication and a device for loading a digital certificate in SSL / TLS communication. Background technique [0002] Based on emerging applications such as e-commerce and online banking, it greatly facilitates people's daily life and is favored by people. Since these applications all need to carry out online transactions on the network, they put forward higher requirements for the security of network communication. Therefore, HTTPS (Hyper Text Transfer Protocol over Secure Socket Layer, Hypertext Transfer Security Protocol) has been used by more and more websites. [0003] HTTPS is a security-oriented HTTP (Hypertext transfer protocol, hypertext transfer protocol) channel, that is, adding SSL (Secure Sockets Layer, secure socket layer protocol) or its subsequent version TLS (Transport Layer Security, secure tr...
