%X 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.
