Digital Signature and Proxy Digital Signature Based on Elliptic Curve
Wei Ji · Jisuanji gongcheng · 2008
This paper presents an improved digital signature scheme based on elliptic curve.The security and complexity of digital signature is analyzed.This proposed scheme not only can efficiently resist birthday attack,but also can improve the security of digital signature.In addition,proxy digital signature scheme with its security analysis is proposed.The two message recovery schemes may easily realize with low computation.The paper examines the two schemes by means of examples.
