【摘要】 椭圆曲线加密体制以其特有的优越性被广泛用于数据加密和数字签名。亦用于构造群体数字签名。本文提出了基于有限域GF(2n)上非超奇异椭圆曲线上的群体数字签名和群体肓数字签名,其安全性建立在有限域GF(2n)上非超奇异椭圆曲线的椭圆曲线离散对数问题之上的,且具有一定的实用价值。更多还原

【Abstract】 The elliptic curve cryptosystem with its speciality is widely applied to encryption and digital signature.it is used to construct digital multisignature.In this paper we propose digital multisignature and multiblind digital signature based on non-supersigngular elliptic curve over finite field GF(2n),the safety of these scheme is depend on the discrete logarithm of non-supersingular elliptic curve ,it is suitable for some practice.更多还原
