In 2004, Kim, Huh, Hwang and Lee proposed an efficient key agreement protocol for secure authentication. In this paper, we shall show that their proposed protocol cannot resist th...
Abstract—In this work we consider two protocols for performing cryptanalysis and security enhancement. The first one by Song, is a password authentication scheme based on smart ...
Abstract. Starting from algebraic properties that enable guessing lowentropy secrets, we formalize guessing rules for symbolic verification. The rules are suited for both off-line ...
Password-based protocols for authenticated key exchange (AKE) are designed to work despite the use of passwords drawn from a space so small that an adversary might well enumerate, ...
This paper presents an efficient password-based authenticated encrypted group key agreement protocol immune to dictionary attack under the computation Diffie-Hellman (CDH) assumpt...
