摘要: 基于RSA加密体制,提出了一个可防欺诈的动态门限多重秘密共享方案。该方案能够实现多重秘密共享,灵活地更新群组密钥,动态地加入新的参与者。在方案的实现过程中,能及时检测和识别分发者对参与者以及参与者之间的欺骗行为,从而提高了重构秘密的成功率和方案的实用性。

Abstract:

The paper proposes a dynamic threshold multi-secret sharing scheme based on RSA cryptographic system.In this scheme,multi-secret can be shared.The shadows needn’t be changed when the shared secret is renewed or new participants are added.Moreover,the paper proposes the efficient solutions against multiform cheating,therefore the scheme is high security and practicality.
