An Efficient Universal Designated Verifier Signature Proof
Yumin Wang · Dianzi xuebao · 2006
Joonsang Baek et al.proposed a new type of universal designated verifier signature(UDVS) which is called universal designated verifier signature proof(UDVSP).We present an efficient UDVSP scheme based on Zhang-Safavi-Susilo(ZSS) signature scheme.Using the properties and pre-computing of the bilinear pairings,our proposed scheme only needs two parings computations.Furthermore the scheme uses general cryptographic hash function,and does not require special hash function(Map to Point).The security of our UDVSP scheme is then proven in the random oracle model.
