Proactive Multi-secret Sharing Scheme

Verifiable proactive secret sharing constitutes an essential part of any social secret sharing scheme . To the best of our knowledge , there is only one proactive multi-secret sharing scheme (PMSSS) in the literature proposed by Feng et al. in 2015 . Unfortunately , there are two drawbacks in this PMSSS . First , we have to assume that the dealer is trusted and second , the structure used in this scheme makes it unsuitable for social secret sharing schemes . In this paper , we propose the first verifiable proactive multi-secret sharing scheme which overcomes both of these drawbacks .
