hyperelliptic curve discrete logarithmic problems 超椭圆曲线离散对数问题
Up to now most of the known proxy digital signature schemes are based on discrete logarithmic problems or big number factorization problems.
现有的代理数字签名方案大多是基于离散对数问题和大数因子分解问题的方案。
The scheme is based on elliptic curve discrete logarithmic problems, with the merits of high security, small private key and easy to carry out.
