A New Authenticated Key Agreement Protocol for Wireless Mobile Networks

Abstract

For secure communications over wireless mobile networks, Lu et al proposed their secure authentication key agreement protocol. However, Lu et al’s protocol is vulnerable against Chang and Chang’s parallel guessing attack. To remove the parallel guessing attacks, Chang and Chang also proposed their improvement. However, Chang and Chang’s protocol is still vulnerable against their parallel guessing attack. So our new authenticated key agreement protocol for wireless mobile networks is proposed.
