中文摘要：
通用指明的验证器签名策划允许一个签名持有者指明到一个愿望的签名指明了验证器，以那个仅仅指明的验证器能验证这签名的如此的一个方法，但是是不能的使其他人相信这个事实。通用指明的验证器签名的以前的构造依靠内在的公钥基础结构，那需要签名人和验证器验证公钥的真实性，并且因此，证书被要求。这篇文章介绍无证书的通用指明的验证器签名计划，证书不在被需要的第一个模型和构造。建议计划在无证书的系统满足通用指明的验证器签名的所有要求。安全证明基于随机的神谕模型被为计划提供，假设双线性的 diffie-hellman (BDH ) 问题是难的解决。
英文摘要：
Universal designated verifier signature schemes allows a signature holder to designate the signature to a desire designated verifier, in such a way that only designated verifier can verify this signature, but is unable to convince anyone else of this fact. The previous constructions of universal designated verifier signature rely on the underlying public key infrastructure, that needs both signers and verifiers to verify the authenticity of the public keys, and hence, the certificates are required. This article presents the first model and construction of the certificateless universal designated verifier signature scheme, in which the certificates are not needed. The proposed scheme satisfies all the requirements of the universal designated verifier signature in the certificateless system. Security proofs are provided for the scheme based on the random oracle model, assuming that the Bilinear diffie-hellman （BDH） problem is hard to solve.
