Efficient Certificate-Based Signature Scheme
In this paper, we give the secure model of certificate-based signature (CBS) and propose an efficient CBS scheme. The proposed scheme is shown to be existentially unforgeable against adaptive chosen message and identity attacks under the discrete logarithm assumption in the random oracle model. Compared with the schemes in RSA 2004 and in EuroPKI 2007, no pairing computation and the special MapToPoint hash function is needed in all phase, and hence, our scheme is more efficient.
