The paper discusses XML security key technologies related with security of Web service. Based on these discussions, Web service is integrated with some mature security architecture...
In 2004, Yoon et al. proposed a user authentication scheme based on generalized ElGamal signature scheme using smart cards. In their scheme, the previous session keys will be comp...
Abstract—In this work we consider two protocols for performing cryptanalysis and security enhancement. The first one by Song, is a password authentication scheme based on smart ...
Fail-stop signature (FSS) schemes are important primitives because in a fail-stop signature scheme the signer is protected against unlimited powerful adversaries as follows: Even i...
Constructing practical and provably secure group signature schemes has been a very active research topic in recent years. A group signature can be viewed as a digital signature wit...
