Cryptanalysis of Guo et al.s three-party password-based authenticated key exchange (G-3PAKE) protocol

摘要：

In 2008, Guo et al.have shown that Lu and Caos simple three-party protocol for passwordauthenticated key exchanges (S-3PAKE) is indeed completely insecure against a kind of man-in-themiddle attack and the undetectable on-line password guessing attack.In addition, they have provided an improved protocol (G-3PAKE) that addresses the identified security problems. However, this paper demonstrates G-3PAKE protocol still falls to undetectable on-line password guessing attack by any other client.
