Joonsang Baek等人提出了一种新型的广义指定验证者签名(UDVS)称为广义指定验证者签名证明(UDVSP).本文提出一个高效的基于Zhang-Safavi—Susilo(ZSS)签名方案的广义指定验证者签名证明.利用双线性对的性质和预计算,所提方案中仅仅需要2个对运算,同时只使用通常密码学上的hash函数,而不需要特殊的hash函数(映射到点).在随机预言机模型中,证明该方案是安全的.
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.
