Method and system for non-contact dynamic password authentication

Abstract

The invention provides a method and a system for non-contact dynamic password authentication and aims at solving the problems of inconvenient operation and low safety of the existing dynamic password authentication. The method comprises the following steps: when the user initiates authentication, an intelligent terminal encrypts the current authentication factor and sends the authentication factor to a dynamic token by use of own first near-field transmission module; the dynamic token receives and decrypts the authentication factor, generates a first dynamic password according to the authentication factor, own key seed and a predetermined dynamic password generation algorithm and sends the first dynamic password to the intelligent terminal; the intelligent terminal receives the encrypted first dynamic password and descripts the first dynamic password, and then sends the first dynamic password to a background server; the background server synchronously generates a second dynamic password, carries out authentication and returns an authentication result to the intelligent terminal. The method for non-contact dynamic password authentication does not require manual operation in the authentication process; in addition, the data need to be encrypted before near-field transmission so that the security of the data can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a non-contact dynamic password authentication method and system method. Background technique [0002] With the development of information technology, the application of information security technology in various fields is more extensive and in-depth. In the field of information security, identity authentication is often the first key used by information systems, and its security has received more and more attention. Correspondingly, in order to strengthen the security of identity authentication, the dynamic password technology has been increasingly applied in various fields, especially in the fields of Internet finance, online games, and telecommunications. In addition, the application of dynamic passwords in enterprises is also a current hotspot. More and more enterprises use dynamic passwords to protect their VPNs, servers, and network devices. [0003] However, ...
