This paper proposes a certificateless designated verifier signature scheme in standard model.Combining the certificateless cryptosystem with designated verifier digital signature,with the properties of bilinear pairings to solve the key escrow problem of ID-based cryptography and certificate authorities in traditional public key cryptography.Under the standard model,it proves that it is provable secure against adaptive chosen-message attack under the hardness assumptions of CDH problem and CBDH problem.
