How to Split a Secret into Unknown Shares

Ruxandra F. Olimid

Abstract: Grigoriev and Shpilrain recently considered secret sharing systems for which nobody (including the dealer) knows the share of a particular party and introduced a construction for the special case of all-or-nothing schemes. We extend their work and propose two threshold secret sharing schemes that satisfy this property.
