Embodiment Construction

[0071] Taking the banking system as an example below, the present invention will be further described in detail in conjunction with the accompanying drawings.

[0072] 1. System Structure Description

[0073] FIG. 1 is an overall structural diagram of the authentication system, including a user terminal 6, a user information server 1, an authentication server 2 and a mobile phone token 5. User information server 1 is the data server in the system, using the oracle9i database system, which stores the form set according to the identity authentication protocol, and provides each user information required in the authentication process. It includes the following fields: ID number, user ID, registration password Pr, encryption and decryption key Ke, current work password Ks (the same as the current work password stored in the mobile phone token), the sign that the account is being used ( prevent competitive attacks) and mobile phone numbers, etc. The user information server 1 rece...

Abstract

The invention discloses a kind of dynamic identification certificating method and system. The steps are: 1. inputs the user's information, and sends out certification query to the server; 2. the server receives the query, verifies the validity of the user's information, instructs the legal user to input the terminal code; 3. the user generates the terminal code through the mobile phone token; 4. the user inputs the user terminal code through the user terminal and transmitted to the certification server; 5. if the code received by the certification server is consistent to the generated one, then it passes the identification certification; otherwise, it won't pass. The system includes a user terminal, the user information server, the certification server and mobile phone token. The certification server receives and completes the service application of the user; the mobile phone token is used to generate synchronous identification certificating code.

Description

technical field [0001] The invention belongs to information security authentication technology, which is realized by comprehensive utilization of electronic computer, information coding and mobile communication technology, and can be applied to many systems and fields requiring identity authentication such as banks and securities. Background technique [0002] Identity authentication is one of the important mechanisms to achieve network security. In secure network communication, all parties involved in the communication must pass some form of identity authentication mechanism to verify whether their identities are consistent with what they claim, and then they can achieve different User access control and logging. As early as the early 1970s, the International Bank Card Association encountered the problem of how to authenticate users to ensure system security. With the rapid development of information technology, eavesdroppers can use low-level peeping methods to obtain pas...
