Abstract
The notion of Universal Designated Verifier Signatures (UDVS) was introduced in the seminal paper of Steinfeld et. al. in [6]. In this paper, we firstly propose a model of identity-based (ID-based) UDVS schemes.We note that there are twomethods to achieve an ID-basedUDVS scheme. We provide two constructions of ID-based UDVS schemes based on bilinear pairings that use the two methods that we have identified. We provide our security proof based on the random oracle model.
