[0045] The implementation method provided by this embodiment includes the following steps:

[0046] Step S201, the dynamic token receives the seed deformation instruction to generate an application code, and submits the application code and token serial number to the application authentication center;

[0047] Step S202, the application authentication center submits the received application code and token serial number to the token center;

[0048] Step S203, the token center generates a deformation factor according to the basic seed in the dynamic token and the received application code and token serial number, and returns the deformation factor to the application authentication center;

[0049] St...

Embodiment 3

[0071] Figure 5 The flow of the implementation method of the multi-key dynamic token provided by the third embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for convenience of description.

[0072] This embodiment uses the dynamic token side to describe the implementation method of the multi-key dynamic token, specifically including:

[0073] Step S501, receiving the seed deformation instruction to generate an application code, and submitting the application code and token serial number to the application authentication center;

[0074] Step S502, receiving the deformation code input by the user, and combining the basic seed, the application code and the deformation times information of the basic seed to generate a deformation seed and save it locally.

[0075] The above two steps describe the basic seed activation process of the dynamic token on the side of the dynamic token, obtain multiple deforma...

Abstract

The invention is applicable to the technical field of identity authentication and provides a method and a device for implementation of a multi-key dynamic password. The method includes: a dynamic password receives a seed transformation instruction, generates the instruction to an application code and submits the application code and a password serial number to an application authentication center; the application authentication center submits the received application code and the password serial number to a password center; the password center generates a transformation factor according to a basic seed in the dynamic password and the received application code and the password serial number, and returns the transformation factor to the application authentication center; the application authentication center generates a transformation code and an authentication center seed according to the transformation factor; and the dynamic password receives the transformation code inputted by a user, generates a transformation seed by combining the basic seed and the application code and stores the transformation seed to the local. The method and the device are capable of completing identity authentication of multiple applications by the aid of one dynamic password, single dynamic password is portable and not easy to lose, and total cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of identity authentication, in particular to a method and device for realizing a multi-key dynamic token. Background technique [0002] In the Internet age, more and more attention has been paid to the security of identity authentication, and the dynamic password technology of corresponding strong identity authentication has been more and more applied in various fields. The characteristic of a dynamic password is that the password is only available once and is time-sensitive. Even if an attacker obtains several passwords of the user through various means, he cannot log in. The current mainstream dynamic password generation mechanisms are: event-synchronized dynamic password, time-synchronized dynamic password, and challenge-response dynamic password. [0003] At present, each type of dynamic token has a built-in basic seed when it leaves the factory. The serial number of the dynamic token is uniquely bound ...
