Embodiment Construction
[0049] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further explained below in conjunction with specific drawings.
[0050] See figure 1 , The seed key involved in the present invention is mainly generated by the key generation system shown, and the system includes:
[0051] Production seed key generation module 11: used to generate the production seed key SeedFactory injected during dynamic token production.
[0052] Seed file assembly module 12: Use the production seed key SeedFactory and serial number generated by the production seed key generation module, as well as other token information, to assemble the seed file, which can also be encrypted during assembly.
[0053] The function of the system is to generate a seed file containing SeedFactory. The role of the seed file includes: first, for token production, injecting tokens through SeedFactory; second, import...

The invention discloses a dynamic token possessing seed automation deformation, a dynamic password authentication system and a method thereof. A dynamic token manufacturer injects a seedfactory during production. After being produced, a token can deform the seedfactory automatically by using a self random factor or a algorithm so as to obtain a seedwork. In the authentication system, firstly, the seedfactory is led in; when or after the token is issued to a client and when the dynamic password authentication is performed, an authentication system acquires the seedwork through many times of attempts and operations according to input tokencode and seedfactory stored in the system. Therefore, the seed deformation of an authentication system terminal can be realized. In the invention, automatic deformation of the seed is a basis. A safety problem of leaks to a whole information system caused by the seed can be effectively solved.
Description
Technical field [0001] The invention relates to information security technology, in particular to a dynamic token device, a dynamic password authentication system and corresponding implementation methods. Background technique [0002] Identity authentication is the foundation of any information system security, and its responsibility is to grant legitimate users access to it while denying access to illegal users. If there is a security problem in identity authentication, other security measures will be useless. [0003] Password authentication is to conduct identity authentication through whether the password is correct or not. It is one of the most common ways of identity authentication. Password authentication can be divided into static password authentication and dynamic password authentication. [0004] Static passwords have many security risks, such as repeated use and susceptibility to Trojan horse attacks, and their security has been generally questioned. More and more impor...
