Abstract

In a designated verifier proxy scheme, a user delegates his signing capability to another user in such a way that the latter can sign messages on behalf of the former, but the validity of generated signatures can only be checked by the designated verifier. In this paper, we first formally defined the concept, then we present a efficient DVPS scheme and show its security property in the random oracle model.
