摘要 提出改进共轭签名体制.基于简单共轭签名体制和共轭签名体制,利用辫群左子群和右子群元素的可交换性,结合随机化因子b,得到了新的共轭签名体制.分析表明该体制不但解决了k-CSP问题,并且与共轭签名体制相比节省了运算次数和通信带宽. A new enhanced conjugate signature scheme （ECSS） is proposed. Based on the simple conjugate signature scheme （SCSS） and conjugate signature scheme （CSS）, the enhanced conjugate signature scheme is brought forward utilizing the randomization factor b and the interchangeaility of the group operation between the elements in the left subgroup and the right subgroup of a braid group. Analysis shows that the new scheme solves the k-CSP vulnerability of SCSS and has a significant reduction on operations and the communication bandwidth comoared with the CSS scheme.
