	abstract = {Protocols for password-based authenticated key exchange (PAKE) allowtwo users who share only a short, low-entropy password to agree on a cryptographically strong session key. The challenge in designing such protocols is that they must be immune to off-line dictionary attacks in which an eavesdropping adversary exhaustively enumerates the dictionary of likely passwords in an attempt to match a password to the set of observed transcripts.
To date, few general frameworks for constructing PAKE protocols in the standard model are known. Here, we abstract and generalize a protocol by Jiang and Gong to give a new methodology for realizing PAKE without random oracles, in the common reference string model. In addition to giving a new approach to the problem, the resulting construction offers several advantages over prior work. We also describe an extension of our protocol that is secure within the universal composability~(UC) framework and, when instantiated using El Gamal encryption, is more efficient than a previous protocol of Canetti et al.
