Embodiment Construction

[0037] At present, dynamic tokens and USBKeys are common choices in realizing user identity authentication technologies. Because dynamic tokens do not need to install any software on the user's client, they can meet the requirements of the Internet and mobile Internet application systems, such as It can be used on PCs and smartphones at the same time, so it is favored by users. However, due to the current challenge-response dynamic token whose security can meet the requirements of the system, the way to generate the dynamic password must allow the user to input keys, which greatly affects the convenience of use of this product. And anyone who gets a dynamic token can use this device, so there is also a risk in security.

[0038] In order to solve the above problems, the embodiment of the present invention provides a dynamic password generation device and method, which realizes the production of dynamic passwords without the need for users to press keys, solves the problem of e...

Abstract

The invention provides a dynamic password generation device and method, relates to the field of information security, and solves the problem that an existing token is not convenient. The dynamic password generation device comprises a central processing unit (CPU), a sensor module and a peripheral display device, wherein the CPU is connected with both the sensor module and the peripheral display device; the sensor module is used for generating external information of the dynamic password generation device through collected dynamic passwords, quantifying the external information, and then sending the external information to the CPU; the CPU is used for receiving the quantified external information sent by the sensor module, generating dynamic passwords according to the external information, and outputting the dynamic passwords to the peripheral display device; the peripheral display device is used for displaying the dynamic passwords output by the CPU. The technical scheme provided in the invention is applicable to identity authentication dynamic tokens, and achieves convenient and safe dynamic tokens.

Description

technical field [0001] The invention relates to the field of information security, in particular to a device and method for generating a dynamic password. Background technique [0002] With the rapid development of computer technology, Internet and mobile Internet technology, domestic enterprise groups, government agencies and financial institutions are using the Internet to establish a fast and efficient network channel between themselves and the public, providing people with various applications Serve. Because it is an information service based on the Internet, the security of the application system is particularly important. In terms of improving system security, user identity authentication is a necessary and important key link. At present, dynamic tokens and USBKeys are common choices in realizing user identity authentication technologies. Because dynamic tokens do not need to install any software on the user's client, they can meet the requirements of the Internet an...
