Title: Anti-cheat and Dynamic(t,n) Threshold Secret Sharing Scheme
Abstract: Aiming at the shortages that GT threshold secret sharing scheme needs security channel,and participants can not directly verify each other information,this paper proposes an anti-cheat and dynamic(t,n) threshold secret sharing scheme based on RSA and discrete logarithm cryptosystem,a two-variable one-way function and circle property.It is able to verify whether all participants are honest and every participant is also able to check whether others' secret shares are valid.It can reduce the steep of reconstruction,and enhances the possibility of secret reconstructions' success.In the whole dynamic process,the center of circle and secret shares always stay the same,which reduces the cost of realizing the schemes,makes the scheme have highly security and practicality.
