Forward-secure Ring Signature Based on Conic Curve over Z_n
Chunguang Ma · Jisuanji gongcheng · 2008
A new concept called forward-secure ring signature scheme based on conic curve over Zn is proposed. The scheme considers the key exposure problem, and adopted difficulties of factoring large integer and computing discrete logarithm, which strengthens the performance of the security. Because the whole signature is operated in conic curve over Zn, the scheme is easier to accomplish for embedding plaintext, computing element order and points in curves, and speeding up the inverse operation.
