A New Authenticated Key Agreement Protocol for Wireless Mobile Networks

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.
