A New Provably Secure Certificateless Signature Scheme
Certificateless public key cryptography was introduced by Al-Riyami and Paterson to overcome the key escrow problem of ID-PKC. In this paper, the authors present an efficient certificateless signature scheme using bilinear maps. The scheme can be proved secure in the strongest security model of certificateless signature schemes. In terms of computational cost, totally, only two pairing operations are required for signing and verification. It is more efficient than the other existing certificateless signature schemes secure against a super type I/II adversary.
