Certificateless signature scheme provably secure in standard model
Qian Xue-zhong · Computer Engineering and Applications Journal · 2008
Certificateless Public Key Cryptography(CL-PKC) eliminates the inherent key escrow problem of Identity-Based Cryptography(IBC),while preserving the attractive advantage of IBC which dispenses with certificates of traditional Public Key Cryptography(PKC) and their costly management overhead.In this paper,the author propose an efficient concrete certificateless signature scheme that is provably secure against strong adversaries in the standard model,and that can be implemented on wider elliptic curves suitable for pairings.
