Abstract

The invention provides an anti-repudiation dynamic password generating method and an anti-repudiation dynamic password generating system. The method comprises the following steps that S1, a client acquires time information and place information and transmits the time information and the place information to a server; S2, the client generates a first dynamic password according to the time information and the place information, and transmits the first dynamic password to the server; S3, the server generates a second dynamic password according to the time information and the place information; and S4, the server compares the first dynamic password with the second dynamic password, and if the first dynamic password is the same as the second dynamic password, the comparison is successful. According to the method provided by the invention, the current time and place of the client are acquired by a satellite, and the time information and the place information are used as key elements for generating dynamic passwords, so that the dynamic passwords have anti-repudiation properties.

Description

technical field [0001] The invention relates to the field of information security, in particular to an anti-repudiation dynamic password generation method and a dynamic password verification system. Background technique [0002] 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 the 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. [0003] Dynamic password is an unpredictable combination of random numbers generated according to a special algorithm. A password is valid once used. It is currently widely used in online banking, online games, telecom operators, e-government, enterprises and other application fields. Dynamic password is a safe and convenient account anti-theft te...
