Strongly Unforgeable Threshold Signature Scheme in the Standard Model
Jun Li · Microcomputer Information · 2010
In this paper,the authors propose a strongly unforgeable threshold signature scheme using Gennaro's distributed key generation protocol and based on Boneh-Shen-Waters(BSW) signature scheme.Its security is based on Computational Diffie-Hellman(CDH) assumption.Because BSW scheme can not transfer to a threshold signature directly,a trusted third part is added to realize the transformation.
