TCP long connection security verification encryption method

Abstract

The invention discloses a TCP (Transmission Control Protocol) long connection security verification encryption method, which mainly comprises the following steps that: 1, a client is connected with aserver by utilizing a TCP, and simple identity authentication is carried out after connection; 2, encryption is carried out in a handshake re-authentication mode, that is, after the client is connected with the server, the identity label of the client and the random code server are sent to the server, and the server verifies the legality of identity representation after receiving the identity label and the random code server; and then the two parties start a handshake process of simple encrypted transmission. The method is wide in application and high in applicability, the client can be connected with the server in the production environment and the research and development environment, and the method can be used for various application scenes such as embedded equipment, software activation and account login.

Description

technical field [0001] The invention belongs to the technical field of SSL data encryption, and in particular relates to a TCP long connection security verification encryption method. Background technique [0002] The SSL (Secure Sockets Layer, Secure Sockets Layer) protocol, developed by Netscape Communications, is a security protocol that provides security and data integrity for network communications. SSL encrypts network connections at the transport layer to ensure the security of network data transmission, and uses data encryption (Encryption) technology to ensure that data will not be intercepted and eavesdropped during network transmission. The SSL protocol is required to be based on a reliable transport layer protocol (TCP). The SSL protocol has completed encryption, communication key negotiation and server authentication before the application layer protocol communication. After that, the data transmitted by the application layer protocol will be encrypted to ensur...

Problems solved by technology

[0003] However, the current SSL data encryption transmission technology generally has the following defects: (1) SSL certificates need to be paid for application; (2) SSL connection caching is not efficient, which will increase certain traffic costs; (3) SSL connections occupy a lot of system resources, especially servers end, the number of SSL connections will be much less than the number of non-SSL connections; (4) SSL occupies too much space, memory and CPU in embedded devices with tight system resources, which will cause the entire system to freeze; (5) SSL The data is transmitted after the client and the server complete the handshake protocol, and there is a vulnerability of a large number of malicious SSL connections
