As prior secret sharing can not provide forward-secure. So in this paper a forward secure secret sharing scheme is proposed to achieve security against cheating participants by using multiplicative threshold scheme of Boyd, based on discrete logarithms and the strong RSA assumption. In the scheme participants can update and verify the shares. Security of the scheme is provided under the strong RSA assumption and discrete logarithms.
