Abstract

Many existing password-based group key exchange protocols use the symmetric ciphers and Hash functions to maintain their security. An efficient and provably secure password-based group key exchange protocol, using only Hash function, is proposed. It is semantically secure against off-line dictionary attacks in the random oracle model and is more efficient than the related works.
