| Abstract: | Compared with traditional static password system,the identity authentication system with dynamic password is more secure.Based on ElGamal's private key cryptosystem and challenge-response mechanism,this paper presents a new identity authentication scheme with dynamic password which integrates the smart card and the fingerprint features.The bidirectional authentication between the clients and the server is also achieved.This scheme is effective in preventing reply attack and masquerade attack. |
