На Ченг · Jisuanji gongcheng yu sheji · 2012
After analyzing the present threshold signature schemes and verifiable secret sharing(VSS) methods,an identity based on VSS method is proposed.According to those problem that most of present threshold signature schemes based on discrete logarithm and elliptic curve difficult to apply to the system with large-scale members because of low efficiency and security,a new identity-based threshold verifiable signature scheme using VSS is proposed.The new scheme avoids the complex mathematical computations and is more efficient.The scheme is proved to be effective against some common attacks such as key recovery attacks,equation attacks,collusion attacks,impersonation attacks and so on.
