Enhanced of Simple Three Party Key Exchange Protocol: Attacks and a Solution
Abstract: In secure communication password based three party encrypted key exchange (3PEKE) protocols have become significant due to the simplicity of maintaining human memorable passwords. In 2007, Lu and Cao proposed a simple and efficient three party password based authenticated key exchange (S-3PAKE) protocol. In 2008, Guo et al. found that S-3PAKE protocol has some loop holes and attacked by man in the middle attack and on-line dictionary attack. They proposed …

Cryptanalysis of Modified STPKE’ Protocol
Abstract: ABSTRACTIn 2007, Lu and Cao proposed a simple 3-party authenticated key exchange (S-3PAKE) protocol. Kim and Koi found that this protocol cannot resist undetectable online password guessing attacks and gave fixed STPKE’ protocol as a countermeasure using exclusive-or operation. Recently, Tallapally and Padmavathy found that STPKE’ is still vulnerable to undetectable online password guessing attack and gave a modified STPKE’ protocol. In this article, we show that the improvement that …
