Abstract: We present an efficient password-authenticated key exchange protocol which is secure against off-line dictionary attacks even when users choose passwords from a very small space (say, a dictionary of English words). We prove security in the standard model under the decisional Diffie-Hellman assumption, assuming public parameters generated by a trusted party. Compared to the recent work of Goldreich and Lindell (which was the first to give a secure construction, under general assumptions, in the standard model), our protocol requires only 3 rounds and is efficient enough to be used in practice.
