摘要: 基于RSA密码体制和Pinch方案[12]提出了一种动态广义秘密共享方案。方案可以防止分发者和参与者的欺诈;一个参与者秘密份额的泄漏不会影响其他成员秘密份额的安全性;当更新秘密后,参与者各自的秘密份额可以重用;方案不需要安全信道,降低了系统代价。
关键词: 密码学, 广义秘密共享, 动态秘密共享, RSA密码体制, 可验证性
Abstract: A new dynamic general secret sharing scheme,based on the RSA cryptosystem and the Pinch’s scheme,is proposed in this paper.The scheme can identify the cheaters no matter she/he is the dealer or the participant;the leakage of the shadow of a participant will not affect the security of other participants’ shadows;the shadows can be reused when refreshing the secret;no security channel exists between the dealer and the participants,the property lower the costs of the system.
Key words: cryptography, general secret sharing, dynamic secret sharing, RSA cryptosystem, verification
