Abstract

The notion of Universal Designated-Verifier Signatures was put forth by Steinfeld et. al. in Asiacrypt 2003. This notion allows a signature holder to designate the signature to a desired designated-verifier. In this paper, we extend this notion to allow a signature holder to designate the signature to multi verifiers, and hence, we call our scheme as Universal Designated Multi Verifier Signatures. We provide security proofs for our schemes based on the random oracle model.
