Thesis, Hebrew University, 1988. These new techniques can require more interaction among players, even for linear operations. In this subsection, we will survey some of the non cryptographic secure distributed computation protocols that have been developed. Thesis, Hebrew University, 1988. In a secret sharing system, the set of the subsets of the shareholders, that are allowed to restore the secret, is called the access structure.
Threshold schemes constitutes an important part in secret sharing systems.
The threshold value k can be any value between 1 and n, where n is the total number of shareholders. Most of the secret sharing schemes support some extra features which become important in some applications. 1089-1109, November 1994. However, what is true for standard signature schemes is not true for weak signature schemes. They provide a form of authentication for which the on line participation of a third party is needed.
