%X This paper introduces a natural paradigm for fair exchange protocols,called ID-based partial proxy signature scheme. A security model with precise and formal definitions is presented,and an efficient and provably secure partial proxy signature scheme is proposed. This is a full ID-based optimistic fair exchange protocol. Unlike the vast majority of previously proposed protocols,this approach does not use any zero knowledge proofs,and thus avoids most of the costly computations.
