Certificate-based encryption combines public key encryption and identity-based encryption while it preserves their features.Based on computational Diffie-Hellman assumption,using bilinear pairing,this paper constructed a new certificate-based signature scheme.The security of the scheme had been proved under the random oracle model.The scheme was efficient to be used in the power and bandwidth limited environment,since its signing algorithm did not need the computation of the bilinear pairing and the verification algorithm needs that computation only once.
