Abstract
Abstract. We propose a new general approach to the construction of on-line non-transferable signatures introduced by Liskov and Micali. Our approach is based on an extension of designated verifier proofs which provides interaction simulatability as opposed to transcript simulatability. We then propose a concrete on-line non-transferable scheme which is proved secure in the standard model. Our scheme allows a less restrictive and more practical operation, is more efficient, and meets a stronger notion of security than the previous approach by Liskov and Micali.
