The Secret Sharing scheme assumes long-lived shares. However the protection provided for such long lived and sensitive shares may be insufficient. The security in a system that is exposed to attacks and break-ins might become exhausted. The goal of the pro-active security scheme is to prevent the adversary from learning the secret or from destroying it. The Shamir’s Secret Sharing is pioneer me...

We propose efficient secret sharing schemes realizing general access structures. Our proposed schemes are perfect secret sharing schemes and include Shamir’s (k, n)-threshold schemes as a special case. Furthermore, we show that a verifiable secret sharing scheme for general access structures is realized by one of the proposed schemes. key words: (k, n)-threshold scheme, general access structure...
