摘要

Most verifiable multi-secret sharing schemes can not distinguish the security classification because of having the common drawback of sharing secrets with the same threshold value. In order to withstand the problem, a novel verifiable dynamic multi-policy secret sharing scheme is proposed, in which the dealer can freely give any sets of group secrets for sharing according to the different threshold values, and the shadows held by the participants are not only reusable but also verifiable. The proposed scheme provides efficient solutions against the malicious dealer and participants. Moreover, the proposed scheme can add new participants and new group secrets. Compared to the current secret sharing scheme, the proposed scheme is more flexible and more practical application.
