Abstract

The present invention discloses a dynamic password generation and verification method and system, and a dynamic password system. The method comprises the steps of obtaining a seed key issued by a dynamic password authentication server in a TEE environment of a terminal, acquiring user identity information and verifying user identity according to the user identity information; and if the verification result is no difference, generating a dynamic password according to the seed key. According to the TEE-based dynamic password system provided by the invention, the dynamic password generation process, the cipher operation process and the user authentication process are performed under the TEE; the sensitive information such as the key of the user, the identity information, the biometric information, the password information and the like is stored through a secure storing module under the TEE, thereby avoiding many problems in the prior art, such as the dynamic password generation process iscarried out in the REE and the sensitive information of the user is stored in the REE environment, thus causing hidden dangers such as privacy leakage and property theft.

Description

technical field [0001] This application relates to the field of information technology, in particular, to a method for generating a dynamic password, a method for verifying a dynamic password, a system for a dynamic password, and a system for generating and verifying a dynamic password. Background technique [0002] In order to improve the identity authentication security of network application systems such as online banking, telephone banking, online securities, telephone securities, online shopping, and online games, various industries and enterprises have introduced dynamic password authentication with higher security than traditional static passwords. system. [0003] The dynamic password identity authentication system is used for identity authentication, which greatly improves the security of the network application system. The current main identity authentication methods and their advantages and disadvantages are: [0004] Dynamic password technology and PKI technolo...
