Two Undetectable On-line Dictionary Attacks on Debiao et al.’s S-3PAKE Protocol

Authors: Eun-Jun Yoon, Sung-Bae Choi, Sang-Yoon Yoon

Abstract:

In 2011, Debiao et al. pointed out that S-3PAKE protocol proposed by Lu and Cao for password-authenticated key exchange in the three-party setting is vulnerable to an off-line dictionary attack. Then, they proposed some countermeasures to eliminate the security vulnerability of the S-3PAKE. Nevertheless, this paper points out their enhanced S-3PAKE protocol is still vulnerable to undetectable on-line dictionary attacks unlike their claim.
