WebA number of mathematical structures have been used to model shared secret schemes. Some of these are polynomials, geometric configurations, block designs, Reed-Solomon codes, vector spaces, matroids, near-right fields, complete multipartite graphs and orthogonal arrays. In most real-world applications there is also a need for a hierarchy to ...

WebIn this scheme, any t out of n shares may be used to recover the secret. The system relies on the idea that you can fit a unique polynomial of degree t − 1 to any set of t points that lie on the polynomial. It takes two points to define a straight line, three points to fully define a quadratic, four points to define a cubic curve, and so on.

Web1 Oct 1997 · In this paper, we will generalize the vector space construction due to Brickell. This generalization, introduced by Bertilsson, leads to secret sharing schemes with rational information rates in which the secret can be computed efficiently by each qualified group. Web5 Apr 2004 · In the information-theoretic sense, Shamir’s scheme [12] is a perfect threshold scheme where knowing only t −1 or fewer secret shadows provides no more information about the secret to an opponent than knowing no pieces. Later, several multi-secret sharing schemes were proposed.
