Certificateless public key cryptography solves the certificate management problem in the traditional public key cryptography and the key escrow problem in identity-based cryptography. RSA is a key cryptography technique and provides various interfaces for the applied software in real-life scenarios. To the best of our knowledge, all of the known certificateless ring signature schemes employed bilinear pairings. But the computation cost of the pairings is much higher than that of the exponentiation in a RSA group. In this paper, we present the first certificateless ring signature scheme without pairing and prove the security in the random oracle model. The security of the scheme is closely related to the RSA problem and the discrete logarithm (DL) problem.
