摘要: 给出一种改进的多重秘密共享的门限方案,在该方案中管理者可以安全有效地共享多个密钥,成员可以根据不同的共享密钥计算不同的子密钥。该方案采用知识签名的方法能够有效地抵御管理者欺骗和成员欺骗,具有良好的可扩展性,是安全且高效的。

Abstract: This paper presents a new multisecret sharing threshold scheme. In the scheme, the dealer can manage any set of multiple secrets for sharing and participants can compute sub-secret for different secrets efficiently and securely. The scheme uses knowledge signature to against cheating by dealer and participants. It is demonstrated that this scheme is secure and efficient.

Key words: multisecret sharing, threshold scheme, authentication
