Description
technical field [0001] The invention belongs to the technical field of network security equipment, in particular to a network terminal security equipment based on an SSL encryption protocol and a method for realizing network terminal security. Background technique [0002] The SSL encryption protocol, also known as the Secure Sockets Layer (SSL) protocol, has excellent encryption performance, and the use of this protocol to transmit data can improve security. The SSL protocol can ensure secure data transmission between the client and the server installed with secure sockets, and can be used in all TCP / IP applications to ensure that application-layer data transmission on the Internet is not monitored, forged and tampered with. [0003] However, the SSL protocol itself is very complex, not only including many complex algorithms, such as encryption algorithms, compression algorithms, etc., but also needs to deal with cumbersome certificate encoding, which increases the burden o...
