Web29 de abr. de 2013 · In terms of share’s capabilities, two classes can be identified-same weighted shares and multi weighted shares. In Shamir’s hierarchical secret sharing scheme the dealer assigns a larger number of shares to users at higher levels of hierarchy, so that higher level users hold more shares than lower level users. WebIn this paper, the definitions are simply as follows.. Multi-Level secret sharing: Higher level participants can help lower participants to get the secret.. Compartmented secret sharing: Each level participants has to get its own secret.(No help from higher level participants) According to this paper. I found that Disjunctive Multi-Level secret sharing is identical to …

Shamir also recognize the concept of a hierarchical scheme, and suggests accomplishing the scheme by giving the participants of the more capable levels a greater number of shares. Some of hierarchical secret sharing schemes are known in … WebHierarchical access structures have been widely adopted in secret sharing schemes, where efficiency is the primary consideration for various applications. How to design an efficient hierarchical secret sharing scheme is an important issue. A famous hierarchical secret sharing (HSS) scheme was proposed by Tassa based on Birkhoff interpolation. canon fisheye 15mm
