Abstract: | A provably secure password-authenticated protocol for group key establishment in the common reference string (CRS) model is presented. Our construction assumes the participating users to share a common password and combines smooth hashing as introduced by Cramer and Shoup with a construction of Burmester and Desmedt. Our protocol is constant-round. Namely, it is a three-round protocol that can be seen as generalization of a two-party proposal of Gennaro and Lindell. |
