Abstract

We suggest an elliptic curve modification of the undeniable signature introduced by D. Chaum and H. van-Antwerpen. The signature generation algorithm is supplemented with a preliminary stage of randomization. For signature verification and disavowal protocols, two options are offered. Theorems showing that these protocols meet their purpose have been proven. A method for converting an undeniable signature into a regular digital signature is described, illustrated by the Schnorr electronic signature scheme as an example.

一个随机模拟的Chaum - van Antwerpen不可否认的签名

我们提出了对D. Chaum和H. van-Antwerpen引入的不可否认签名的椭圆曲线修正。签名生成算法补充了初始阶段的随机化。对于签名验证和拒绝协议，提供了两种选择。证明这些协议符合其目的的定理已经得到了证明。本文描述了一种将不可否认签名转换为普通数字签名的方法，并以Schnorr电子签名方案为例进行了说明。
