摘要
该文提出了一种新的基于椭圆曲线的数字签名方案。该数字签名方案的安全性是基于椭圆曲线离散对数难题上的。作者对该方案进行了安全性分析,发现该方案能有效防止伪造攻击。同时,该方案具有通信成本低、通信速度快、安全性高等特点,适合应用于小型身份认证系统。
In this paper, a new message recovery signature scheme using elliptic curves is presented. The security of the scheme is based on the elliptic curve discrete logarithms. We analyze the security of the scheme and discover it can efficiently prevent saboteurs from forgery attacks. Moreover, it has many advantages such as lower communication costs, less communication time and higher security, therefore, the scheme suits the small identification systems.
