Abstract

The invention discloses a dynamic password device and a working method thereof. The dynamic password device is an intelligent card reader provided with a digital keyboard and a liquid crystal display screen and matched with an intelligent card in use. Specifically, the dynamic password device is started to conduct electrification activation on the intelligent card, a first application ciphertext is obtained by means of signaling interaction between the dynamic password device and the intelligent card and use of a seed secret key stored by the dynamic password device, and a disposable dynamic password is generated based on event synchronization, challenge / answer, trade signature and the like. The dynamic password can be applied to authentication operation of online banks, telephone banks and mobile phone banks, authentication of users of an application system can be conducted on various online complex payment occasions in any place at any time, identity theft, identity illegal use and identity fraud are effectively prevented, and network system safety is improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a dynamic password device and its working method. Background technique [0002] With the development of the network, the importance of network information security is also increasing day by day, and identity authentication technology has been widely used. Among them, the dynamic password authentication method is more and more favored by users. The dynamic password is generally generated by the identity authentication system and sent to the user in the form of SMS or email. The customer enters the dynamic password when logging in or transaction authentication, so as to ensure the security of the system identity authentication and effectively avoid theft of user accounts by hackers and Trojan horses. Network security risks caused by the emergence of passwords and fake websites. [0003] In the process of realizing the present invention, the inventor finds that the prior art ha...
