  • Certificateless public key cryptography isa recently proposed attractive paradigm which combinesthe advantages of both certificate-based and identity-basedcryptosystems as it avoids the use of certificates and doesnot suffer from key escrow. In this paper, we present anew Certificateless designated verifier signature (CLDVS)scheme and provide the security proofs and effciency analysis for our scheme. Based on the proposed CLDVS, thefirst notion and construction of the Certificateless designated verifier proxy signature (CLDVPS) scheme is proposed. It proves that our CLDVPS scheme satisfies all therequirements of the designated verifier proxy signatures inthe certificateless public key cryptography.
