The key exchange protocols using passwords achieved great attention due to their simplicity and e ciency. On the other hand these protocols should resist all types of password guessing attacks, as the password is of low entropy. Recently Lu and Cao proposed a three party simple key ex-change protocol (S-3PAKE). It is an extension of Abdella and Pointchval SPAKE protocol. Later Guo et al. proposed a man in the middle attack and undetectable on-line password guessing attack on the above protocol. They also presented an improved S-3PAKE. In the present paper we have shown that the improved S-3PAKE still su ers from undetectable pass-word guessing attack and discuss the countermeasures to preclude such an attack.
