高效的基于身份的门限签名方案
High-efficient identity-based threshold signature scheme
摘要
Abstract
Based on the signature scheme proposed by Guke,a new ID-based threshold signature scheme is designed,which is efficient and provably secure in the standard model (without random oracle).The generation of the threshold key does not require a trusted third party.The new scheme improves efficiency by reducing multiplicative operations and bilinear pairing operations,especially by precomputing bilinear pairing operation.And the new scheme is against existential forgery under the adaptive chosen message attack under the computation Diffie-Hellman assumption in the standard model.Compared with the current ID-based threshold signature scheme,the new one is more computational efficient.关键词
