  • Method and device for verifying dynamic password
    Patent number: 8850540
    Abstract: The examples of the present invention provide a method and device for verifying a dynamic password. In the method and device, some algorithm parameters can be exchanged in public by using a DH algorithm, and thus a same key is shared safely between two entities, so as to implement the verification of the dynamic password and further improve the security of identity verification. Moreover, the method and device can be easy to use. Further, by the above technical solution, no message exchange is needed between a mobile device and a verification server, and a user does not need to pay for additional flux, so as to decrease the burden of the user and verification costs.
