We describe two new attacks on the HMQV protocol. The firstattack raises a serious question on the basic definition of``authentication'' in HMQV, while the second attack isgenerally applicable to many other protocols. In addition, wepresent a new authenticated key agreement protocol called YAK.Our approach is to depend on well-established techniques suchas Schnorr's signature. Among all the related protocols, YAKappears to be the simplest so far. We believe simplicity is animportant engineering principle.
