Abstract
In 2007, Shim pointed out that AuthA protocol which is in the process of being standardized by IEEE are vulnerable to chosen protocol attacks and then suggested some coun- termeasures against the attacks. In this paper, we demonstrate another vulnerability of Shim´s improved AuthA protocol and then present an improvement to repair the security flaws of the protocol.
