Efficient Certificateless Short Signature Scheme Under Standard Model
摘要
Abstract
Most certificateless signature schemes are inefficient because they need several bilinear parings operations. Aiming at the problem, this paper proposes a new certificateless short signature scheme based on Strong Diffie-Hellman(SDH) problem. It is more efficient because it needs only one bilinear parings operation and one hash operation in signing and verifying processes, and it has the same length as Boneh-Boyen's short signature. It is proved satisfying non-forgeability under two types of adversaries' attacks under standard model.关键词
