Certificateless universal designated multi-verifiers signature scheme
无证书的广义指定多个验证者签名体制*

This paper proposed certificateless universal designated multi-verifier signature schemes,expended a single verifier to a set of multi-verifiers.This scheme satisfied all the requirements of the universal designated verifier signature in the certificateless system.Its security relied on the BDH assumption,and proved under the random oracle model this scheme can resist the adaptively select of message and identity attack.
