New Methods to Construct Cheating Immune Multisecret Sharing Scheme

摘要

In this paper, the constructions of cheating immune secret sharing and multisecret sharing are studied. Based on the theories of matrix and linear block codes over finite field, some new methods to construct cheating immune secret sharing, strictly cheating immune secret sharing and multisecret sharing immune against cheating are proposed. Some cryptographic properties of the constructed secret sharing are analyzed as well.
