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.

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...

Equalization of Loudspeaker and Room Responses Using Kautz Filters: Direct Least Squares Design

DSP-based correction of loudspeaker and room responses is becoming an important part of improving sound reproduction. Such response equalization (EQ) is based on using a digital filter in cascade with the reproduction channel to counteract the response errors introduced by loudspeakers and room acoustics. Several FIR and IIR filter design techniques have been proposed for equalization purposes....
