METHOD AND APPARATUS FOR DYNAMIC PASSWORD VERIFICATION.

摘要

A method and an apparatus for dynamic password verification are provided by the embodiments of the present invention. The Diffieâ Hellman (DH) key exchange algorithm is used in the method, and the same key is shared between two entities safety by exchanging some algorithm parameters in public, thus realizing the verification for dynamic password, improving the security of the identity verification. The method is simple and easy to use. Meanwhile, no message interaction is generated between a mobile equipment and an authentication server, no extra traffic fee is brought, and the user burden and the authentication cost are reduced.
