Strongly Unforgeable Certificateless Signature Scheme in the Standard Model

Certificateless signature scheme eliminates the need of certificates in the traditional signature scheme and solves the inherent key escrow problem in the identity based signature scheme. In this paper, the authors propose a new construction of certificateless signature which is strongly unforgeable in the standard model with the computational Diffie-Hellman assumption in bilinear groups. As far as they know, this is the first certificateless signature scheme, which possesses the property of strong unforgeability in the standard model.
