A New Scheme of Restrictive Group Blind Signature Based on Elliptic Curves
Zhang Qishan · Jisuanji gongcheng · 2005
A new scheme of restrictive group blind signature based on elliptic curve discrete logarithm problem (ECDLP) is forwarded, which extends the restrictive group blind signature and the signature of knowledge to the elliptic curve cyclic group in order to enhance its security and efficiency. And on this basis, a new multi-bank e-cash system is proposed. Analysis testifies its security and efficiency.
