Web communication encrypting method

Abstract

The invention provides a Web communication encryption method, which distinguishes between the first communication and the second communication between the client and the server. When the client accessing for the first time communicates with the server on the Web, it needs to negotiate to determine the communication encryption algorithm, and there is no need to negotiate again when communicating again; when communicating for the first time, the client obtains the communication master key provided by the server and saves the communication master key , when communicating again, the server only needs to calculate and generate the key locally, and the client uses the locally stored communication master key to transmit the session key, and then the two parties use the session key to encrypt and decrypt the communication data to realize confidential communication. The communication encryption method of the present invention greatly reduces the key storage capacity of the server, and the reduction of the key exchange calculation load of the server is also obvious.

Description

technical field [0001] The invention belongs to the fields of computer, communication and information security, and in particular relates to an encryption method for Web communication. Background technique [0002] With the rapid popularization of applications based on the World Wide Web, e-commerce has become a part of people's daily work and life. The growth of the Web has also brought us threats in terms of security and personal privacy. In general situations, web communication processes such as browsing web pages and sending and receiving emails are not able to provide sufficient security protection, which directly leads to the fact that communication data streams can be easily monitored and intercepted, tampered with, and replayed without knowing it, resulting in Serious consequences such as user sensitive information leakage, loss, and Web service failure. [0003] In order to ensure the security of the Web service, the security of the service flow between the client...

AI Technical Summary

Problems solved by technology

Repeated negotiations directly lead to a sharp increase in the computing load of the server, and the increase in processing delays leads to handshake failures, which prevents the establishment of secure connections and seriously affects service quality.

Due to the high cost of key negotiation, the threshold of Web communication encryption is too high, so that many sites cannot provide Web communication encryption services

Therefore, it is difficult to effectively protect the confidentiality of sensitive data and user privacy
