On Hierarchical Threshold Secret Sharing
Ali Aydin Selcuk and Kerem Kaskaloglu and Ferruh Ozbudak
Abstract: Recently, two novel schemes have been proposed for hierarchical threshold secret sharing, one based on Birkoff interpolation and another based on bivariate Lagrange interpolation. In this short paper, we propose a much simpler solution for this problem.
Category / Keywords: Secret sharing, threshold cryptography, hierarchical access structures.
