Many certificateless signature schemes have been proposed to solve the key escrow problem in the ID-based signatures. In this paper, based on discrete logarithm problem and factoring problem, a new certificateless signature scheme is proposed. In our scheme, during the signing phase, it needs not any pairing operation or exponential modular computation. During the verifying phase, it needs two exponential modular operations. Then, compared with the scheme of this kind, our scheme is more efficient. Our scheme can be proved secure in the random oracle. Only both of the factoring problem and discrete logarithm are solved can our signature be forged. Then, compared with the scheme of this kind, our scheme has a stronger security.
