Generalized Secret Sharing using Permutation Ordered Binary System

Secret sharing is a method of dividing a secret among n participants and allows only qualified subset to reconstruct the secret and hence provides better reliability and availability of secret data.In the generalized secret sharing scheme, a monotone access structure of the set of participants is considered. The access structure specifies a qualified subset of participants who can reconstruct the secret from their shares.Generalized secret sharing schemes can be efficiently implemented by using (n, n) scheme.We have developed an efficient (n, n) scheme using Permutation Ordered Binary (POB) number system which is then combined with cumulative arrays to obtain a generalized secret sharing scheme.
