Abstract

The invention provides a two-way identity authentication method and system based on dynamic passwords. The method comprises the steps that an application unit receives user identification and the first dynamic password input from the outside, and the user identification, the first dynamic password and verification information which is stored in advance and is used for verifying the application unit are sent to an authentication unit; the authentication unit receives the user identification, the first dynamic password and the verification information, the first dynamic password is verified according to the user identification, after the verification is passed, identity authentication is conducted on the application unit according to the verification information, if the authentication is passed, the second dynamic password is generated according to the user identification, the second dynamic password is sent to the application unit, and otherwise the second dynamic password is not generated; the application unit receives the second dynamic password, and the second dynamic password is output. The two-way identity authentication method and system based on the dynamic passwords can improve the safety of an application system.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a dynamic password-based two-way identity authentication method and system. Background technique [0002] The dynamic password is an unpredictable combination of random numbers generated according to a special algorithm, and each password can only be used once. As one of the most secure identity authentication technologies, dynamic passwords have been applied by more and more industries. Because it is easy to use and has nothing to do with the platform, with the development of mobile Internet, dynamic password technology has become the mainstream of identity authentication technology, and is widely used in enterprises, online games, finance and other fields. At present, there are four main types of terminals used to generate dynamic passwords: hardware tokens, SMS passwords, mobile phone tokens, and software tokens. [0003] The existing method of identity authenti...
