A (t,n)- threshold secret sharing scheme is a method for distributing a secret amongst a group of participants [1]. Each of participants is allocated a share of the secret. The secret can only be reconstructed when the shares are combined together [6]. In this paper, we propose a secret sharing scheme based on residue class ring Fp[x]/( f ), where p is a prime and deg( f ) = n. Then we call it a (pn −1, pn)− threshold secret sharing scheme.
