Enhanced Forward-Secure User Authentication Scheme with Smart Cards.

In 2006, Wang-Li proposed a new user authentication scheme using smart cards which can offer forward secrecy. However, this paper will demonstrate that Wang-Li's scheme is vulnerable to parallel session attack and reflection attack. Furthermore, the current paper presents a more efficient and secure scheme that not only resolves such problems, but also involves fewer computations and communications than Wang-Li's scheme. Keywords: Network security, Secure protocol, Smart card, Authentication, Password. [ABSTRACT FROM AUTHOR]
