A secure token-updated authentication scheme using security key
2007
Recently, a large number of authentication schemes based on smart cards have been proposed, using the thinking of OTP (one-time password) to withstand replay attack. Unfortunately, if these schemes implement on PCs instead of smart cards, most of themcannot withstand impersonation attack and Stolen-Verifier attack since the data on PCs is easy to read and steal. In this paper, a secure authentication scheme based on a security key and a renewable token is proposed to implement on PCs. A comparison with other schemes demonstrates the proposed scheme has following merits: (1) Withstanding Stolen-Verifier attack (2) Withstanding Impersonation attack (3) Providing mutual authentication; (4) Easy to construct secure session keys.
