Abstract :
Recently, Kwon et al. found that LKY scheme is vulnerable to off-line dictionary attack. They showed that LKY is not a complete PAKA scheme since it is possible for the involved two parties to not share a common session key as a result of executing LKY. In our paper, we will discuss the reasons for the above attack and propose two improved scheme to solve this problem.
