Certificateless Signature

Certificateless signature schemes are a very intriguing aspect in information security because of its capability of removing the well-known key escrow problem predominately in ID-based cryptography. He et al. proposed an efficient certificateless aggregate signature scheme and proved that their scheme is secure against all possible types of security attacks. However, the authors still managed to find loopholes in the form of insecurities against ‘honest but curious' and ‘malicious but passive' attacks during cryptanalysis of He et al.'s scheme. The authors propose an efficient certificateless aggregate signature scheme which fills the security gaps in He et al.'s scheme and demonstrate the security in their scheme via a mathematical proof, and reinforce the fact that their scheme is much more efficient in a thorough performance comparison of their scheme against the previous schemes.
