This paper presents a secure constant-round password-based group key exchange protocol in the common reference string model. Our protocol is based on the group key exchange protocol by Burmester and Desmedt and on the 2-party password-based authenticated protocols by Gennaro and Lindell, and by Katz, Ostrovsky, and Yung. The proof of security is in the standard model and based on the notion of smooth projective hash functions. As a result, it can be instantiated under various computational assumptions, such as decisional Diffie-Hellman, quadratic residuosity, and N-residuosity.
