In 2006, Huang, Susilo, Mu and Zhang proposed the concept of restricted universal designated verifier signatures while Klonowski, Kubiak, Kutylowski and Lauks proposed independently the dual primitive of dedicated signatures. In both notions, a signature holder can convince one or more verifiers of his knowledge of a digital signature, but cannot exploit this knowledge without being punished for that. In this paper, we state that a signature holder may generically provide a proof that it has a certain signature without being punished and that consequently both primitives cannot fulfill their alleged security goals. To demonstrate the feasibility of this claim, we propose the first non-interactive universal designated verifier proof of the possession of an Elgamal or a DSA signature in the random oracle model. This construction may be of independent interest.
