A Verifiable Threshold Signature Scheme Based on Elliptic Curve
Peng Qing-jun · 2008
ECDSA demands calculation of inverse in the finite field,and thus calculation is complex and time-consuming.Moreover,it is difficult to split and synthetic key in this scheme.So it can not be directly applied to threshold signature.By using Pedersen verifiable threshold secret sharing technique,a(t,n) verifiable threshold signature scheme is constructed based on an improved ECSDA.The scheme is of robustness,low in communication cost and high in efficiency etc.The security of this scheme is also discussed.
