Certificateless public key cryptography eliminates inherent key escrow problem in identity-based cryptography, and does not yet requires certificates as in the traditional public key infrastructure. Recently, Yu et al. propose a new certificateless signature scheme and their scheme offers shorter system parameters and higher computational efficiency than the previous schemes in the standard model. However, in this paper, we show Yu et al.'s certificateless signature scheme is vulnerable to malicious-but-passive KGC attack where a malicious KGC can forge valid signatures by embedding extra trapdoors in the system parameter.
