Data encryption communication terminal method and device, terminal, server and storage medium

Abstract

The invention discloses a data encryption communication terminal method and device, a terminal, a server and a storage medium, and the method comprises the steps: continuously executing a multi-time transport layer security protocol handshake process with a server side, and obtaining a plurality of symmetric encryption keys, wherein the message in the second handshake process is encrypted by using a first symmetric encryption key obtained in the first handshake process, a second symmetric encryption key is obtained through the second handshake process, the first handshake process and the second handshake process are any two adjacently executed handshake processes in multiple transport layer security protocol handshake processes, and the first handshake process is executed before the second handshake process; and according to the execution sequence of the multiple transport layer security protocol handshake processes, sequentially using the plurality of symmetric encryption keys to carry out data transmission with the server side. According to the method and the device, the counterfeited server side can be identified, so the data encryption effect is improved, the counterfeited server side cannot correctly decrypt the received encrypted data, and the data transmission security is improved.

Description

technical field [0001] Embodiments of the present invention relate to network communication security technologies, and in particular to a data encryption communication terminal method, device, terminal, server and storage medium. Background technique [0002] With the vigorous development of the Internet and the updating and upgrading of communication technology, a large amount of information needs to be transmitted through the network, which contains a large amount of private information that needs to be protected. In order to ensure the security of information transmission and prevent these important information from being stolen and maliciously used, Data needs to be encrypted during network communication. [0003] At present, the industry standard protocol for confidential communication on the Internet is the Transport Layer Security protocol (Transport Layer Security, TLS), which can provide security and data integrity protection for Internet communications, browsers, m...

AI Technical Summary

Problems solved by technology

[0004] However, the current transport layer security protocol still has the problem of leaking the server-side private key. Since the certificate carrying the public key can be obtained normally, the attacker can use the leaked server-side private key and public key to construct a fake server-side as The real server side steals the private data of the client

It can be seen that there are security loopholes in encryption according to the current transport layer security protocol, and the encryption effect needs to be improved urgently
