The geometry of shared secret schemes
Web5 Apr 2004 · 1.. IntroductionIn 1979, the first (t,n) threshold secret sharing schemes were proposed by Shamir [12] and Blakley [1] independently.Shamir’s scheme [12] is based on the Lagrange interpolating polynomial, while Blakley’s scheme [1] is based on linear projective geometry. In a (t,n) threshold secret sharing scheme, at least t or more participants can … 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 Jun 2001 · A secret sharing scheme is a method for sharing a secret among a set p of p participants. The secret is encoded into n pieces called shares each of which is given to a distinct participant.

The size of the secret is H (S) and of ith share is H (s i) where H is Shannon’s entropy. The pieces of information are called shares and the process responsible for the division is called dealer.
