Later, several multi-secret sharing schemes were proposed. 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. recipe for cauliflower rice mushroom risotto
