Automatic certificate replacement method and communication system without online certification center

Abstract

The invention provides an automatic certificate change method of an offline authentication center and an offline authentication communication system. The automatic certificate change method of the offline authentication center comprises the following steps: in a communication establishment process of a first mobile terminal and a second mobile terminal, respectively sending certificate resources that are used by a present end at the moment to an opposite end to serve as communication establishment request information to complete identity authentication; after the first mobile terminal and the second mobile terminal receive the communication establishment request information of the opposite end, respectively using the current time of the present end as standard to judge whether the certificate resources sent by the opposite end are effective; if so, establishing the communication; and otherwise, interrupting the communication, wherein the judging whether the certificate resources sent by the opposite end are effective comprises judging whether the certificate resources sent by the opposite end are within the service life or within the compatible period of the service life. According to the automatic certificate change method provided by the invention, the certificate resources are designed to change the compatibility, and the hidden danger that normal communication cannot be realized when multiple certificates are not synchronously synchronized, thereby improving the system reliability and stability of the mobile terminal.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a certificate automatic replacement method without an online authentication center and a communication system without an online authentication. Background technique [0002] The open nature of the mobile communication network brings great challenges to its own security. How to ensure the security of communication between mobile terminals has always been an important issue in the field of mobile communication. A feasible solution is to use identity authentication technology to mutually authenticate the legitimacy of the identity of the other end in the process of communication between the two parties, so as to ensure the security of communication. Identity authentication is inseparable from certificates. The original intention of certificates is to use a trusted third party (certification center, usually referred to as CA) to issue a mutually trusted identity to users. Based on ...
