Hierarchical secret sharing
WebHierarchical secret sharing schemes are known for the way the secret is shared among a group of participants that is partitioned into levels. We examine these schemes in terms of how easily they delete a secret after it is distributed or namely for cases where the reliability of data deletion depends on deletion of the indispensable participants' share. WebThe construction of secret sharing schemes has received a considerable attention of many searchers whose main goal was to improve the information rate. In this paper, we propose a novel construction of a secret sharing scheme which is based on the hierarchical concept of companies illustrated through its organization chart and represented by a ...
