A Forward-Secure(t,n)Threshold Signature Scheme Based on the Elliptic Curve Cryptography
Cheng Zhong · Computer Engineering and Science · 2007
This paper presents a(t,n)threshold digital signature scheme based on the elliptic curve cryptography.The scheme can prevent the trusted party from forging the signature,and avoid any t or more members conspiring to filch the group secret key and forge the signature.The scheme has a forward security.
