A non-perfect secret sharing scheme called MIX-SPLIT is a substitution cipher created by mixing two statistically similar binary sequences (secrets) through a codebook. At the heart of the algorithm are the hidden partitions which define the identity of the shares generated. By imposing certain constraints on the codebook these partitions can be made invisible, opening up the possibility of constructing...
In perfect secret sharing schemes, invalid coalitions of shares do not reveal any information regarding the secret. However, in secret sharing constructions which are non-perfect in nature, every illegitimate coalition leaks out information not just pertaining to the parent secret but also related to other shares in circulation. In this paper the information flow and leakage through shares generated...
