Safe authentication and encrypted communication method

Abstract

The invention discloses a safe communication authentication and encrypted communication method comprising three parts: the method for realizing the establishment of a digital signature by a signature institution or a digital publisher, the method for authenticating the signature in application and the method for establishing the encrypted communication in the application. The safe communication authentication and encrypted communication method can conveniently utilize Internet, a public telephone network, and the like for realizing the point-to-point bidirectional digital signature authentication, the encrypted communication function and other functions, thereby ensuring the credibility and the authenticity of both communication parties and realizing the safety and the confidentiality.

Description

technical field [0001] The invention relates to an identity authentication and encryption communication method, in particular to a method for implementing identity authentication and encryption communication by using symmetric and asymmetric encryption algorithms to carry out digital signatures on products. Background technique [0002] With the rapid development of technology and the Internet and global informatization, the security, confidentiality and reliability of some important information are becoming more and more important. How to ensure that the person you are communicating with is a real and credible party, not a disguise or a trap, so as to ensure that both parties can enjoy convenient, confidential, safe and reliable communication through the public communication network. Such application areas include: personal secure communication and commercial and military communication. [0003] The current secure communication either uses large number calculations in asym...
