Perfect Secret Sharing Schemes from Room Squares

Secret sharing schemes are one of the most important primitives in distributed systems In perfect secret sharing schemes collabo ration between unauthorised participants cannot reduce their uncer tainty about the secret This paper presents a perfect secret sharing scheme arising from critical sets of Room squares

Secret Sharing Schemes Based on Room Squares

In this paper, we describe secret sharing schemes. We discuss Room squares and their critical sets. We propose a model of secret sharing based on critical sets of Room squares.

PEDOMODELS FITTING WITH FUZZY LEAST SQUARES REGRESSION

Pedomodels have become a popular topic in soil science and environmentalresearch. They are predictive functions of certain soil properties based on other easily orcheaply measured properties. The common method for fitting pedomodels is to use classicalregression analysis, based on the assumptions of data crispness and deterministic relationsamong variables. In modeling natural systems such as s...

Room squares with holes of sides 3, 5, and 7

We investigate Room squares and subsquares. All terminology is as in [6] and [7], and we will assume the reader is familiar with the definitions contained therein. (These include group-divisible designs, transverial designs, and frames.) We will refer to an incomplete Room square of side s missing a subsquare of side t as an (s, t)-incompZefe Room square. It is known that for any odd t, there i...
