Abstract

This invention discloses a method for authenticating dynamic ciphered codes including: presetting a corresponding relation of the account number of a user and the number of its mobile terminal device, generating a character string randomly according to the request of the user and sending it to the mobile terminal device, generating cipher prompt information randomly according to the authentication application of the user and sending it to the client end stipulating that character combination of specific bits in the string is the dynamic code of the authentication application this time, the user end inputs dynamic codes according to the character string received by the mobile terminal device and the code prompt information received by the client end to judge the validity of the dynamic code, if it is effective, the authentication is passed.

Description

technical field [0001] The invention relates to the field of password authentication, in particular to a dynamic password authentication method and a server system. Background technique [0002] In real life, our personal identity is mainly confirmed by various documents, such as: ID card, household registration book, etc., and various system resources of the computer (such as: files, data, and application systems, etc.) also need to be protected by authentication mechanisms , so as to ensure that these resources are used by the right people. [0003] At present, various types of computing resources are mainly protected by password authentication, generally using static password authentication and dynamic password authentication. [0004] The static password authentication method adopts the "username + password" authentication method. When a user logs in, the application server performs identity authentication through a static password to confirm whether the user is a legi...
