In this paper, we propose a dynamic threshold and verifiable multi-secret sharing scheme. Some secrets are protected by distributing them among many participants, whereby only an authorized group of participants can reconstruct the secrets. In our scheme, the secret will change periodically and the dealer will periodically publish some of the information, in addition, the participants can verify the...
In a (t, n) threshold secret sharing scheme, any t- out-of-n participants could recover the shared secret, and any less than t participants could get nothing about the shared secret. Most of the existing secret sharing schemes are not flexible enough for the fixed threshold. In this paper, a new dynamic threshold secret sharing scheme was proposed, which is based on bilinear maps. The basic idea of...
