Abstract :
In 2003, Hwang et al. proposed an enhanced authentication key exchange protocol. Their protocol can generate multiple shared keys for two entities at a time and takes less computation time than Harn and Lin´s protocol. However, we will show that Hwang et al.´s protocol cannot withstand the forgery signature attack. At the same time, we will repair the security flaw in their scheme.
