摘要 公平性、透明性是联合决策的基本安全需求.结合多机构商务合作背景,利用具有同态性质的Paillier公钥密码系统和门限密码技术,提出了面向有差异群体的联合决策策略与方案,并对其安全性进行了分析和证明. The basic requirements of joint decision-making are fairness and transparency. In this paper, combined with commercial background, a joint decision-making policy and scheme for groups with members having different superiorities is proposed by using PaiUier public key eryptosystem with homeostasis quality based on threshold technique. The newly presented threshold scheme is also proved and examined.
