【Abstract】 A new certificate-based signature scheme is proposed.Assuming the intractability of discrete logarithm problem,the scheme proves to be secure in the strongest security model of certificate-based signature schemes.It requires general cryptographic Hash functions;with no need of any heavily cost bilinear pairing operations in its signing and verifying algorithms.So,it is of advantage of high computation efficiency,and can be used in some power-constrained devices,such as wireless sensor networks.更多还原
