An Improved Scheme for Elliptic Curve Digital Signature

阐述了目前椭圆曲线数字签名(elliptic curve digital signature,ECDSA)存在的问题,针对ECDSA存在的问题提出了改进的方案,并分析了该方案虽然提高了ECDSA的计算效率,但未考虑伪造签名攻击的问题.从椭圆曲线数字签名的安全性和计算高效性出发,提出了一种椭圆曲线数字签名的改进方案,通过理论和仿真实验证明了方案的安全性和高效性.研究结果表明,改进的方案通过标量乘运算2次和逆运算1次,提高了数字签名的计算效率和防止数字签名伪造攻击.

The existing problems of elliptic curve digital signature(ECDSA)are briefly described,the improved scheme for the existing problems of ECDSA is studied,although the scheme improves the computational efficiency of ECDSA,the forgery signature attack is not considered.Based on the security and computational efficiency of elliptic curve digital signature,an improved scheme for elliptic curve digital signature is proposed,the safety and efficiency of the proposed scheme are proved by theory and simulation experiments.The results show that the improved scheme improves the computational efficiency of digital signature and prevents forgery attacks by scalar multiplication twice and inversion once.
