【摘要】 基于Shamir门限方案、RSA密码体制和哈希函数的安全性构建一种参与者有权重的特殊门限秘密共享方案。秘密份额由参与者选择和保存,每个参与者只需维护一个秘密份额即可共享多个秘密。在信息交互过程中不需要传递任何秘密信息,系统无需维持专门的安全信道。理论分析结果表明,该方案安全有效,易于实现。更多还原

【Abstract】 This paper proposes a special threshold secret sharing scheme among weighted participants which is based on the security of Rivest Shamir Adleman(RSA) cryptosystem,Shamir threshold secret sharing scheme and hash function.Each participant’s secret shadow is selected and saved by the participant himself,and he can share many secrets with other participants by holding only one secret shadow.In the process of information exchange,it is not necessary to pass any confidential information and the scheme does not need a secure channel between each participant and the dealer.Theoretical analysis shows that the scheme is secure,effective and easy to implement.更多还原
