Zusammenfassung:Recently, Lee et al. proposed an improvement on Peyravian and Zunic scheme to make the protocol withstand the guessing attack. However, their scheme suffers from a denial of service attack. In this paper, we show that an attacker can easily prevent the normal use of communication facilities by performing the attack. We also propose an enhancement of the scheme to isolate such a problem.
