This paper proposed a verifiable and renewable threshold secret sharing scheme based on bilinear pairings.According to setting up the equation which was verified by both the dealer and the participants,the scheme could identify the validity of the secret share provided by the parties.The dealer could regularly update interpolation polynomial using hash function,so the secret share held by the participants could be regularly updated.Under the assumption of DL problem in finite fields,the shares verification process could prevent from cheating among participants efficiently.
