Title:
Secret Sharing Scheme with Perfect Concealment
Authors: Izumi Takeuti, Tomoko Adachi
Abstract:In 1979, Shamir and Blakley introduced secret sharing schemes to provide both security and reliability.
In this study, we construct two secret sharing schemes with perfect concealment.
The first is an ((n,n))-threshold scheme by a group.
Although the scheme itself is already known, we prove that its concealment is perfect.
We propose the second as a new ((2,n))-threshold scheme by a quasigroup.
