Abstract Abstract: Three-party password authenticated key exchange (3PAKE)
protocol plays a significant role in the history of secure communication
area in which two clients agree a robust session key in an authentic manner
based on passwords. In recent years, researchers focused on developing
simple 3PAKE (S-3PAKE) protocol to gain system efficiency while preserving
security robustness for the system. In this study, we first demonstrate how
an undetectable on-line dictionary attack can be successfully applied over
three existing S-3PAKE schemes. An error correction code (ECC) based S-3PAKE
protocol is then introduced to eliminate the identified authentication
weakness.
