Strongly Multiplicative Hierarchical Threshold Secret Sharing
We consider multi-party computation (MPC) in a hierarchical setting, where participants have different capabilities depending on their position in the hierarchy. First, we give necessary conditions for multiplication of secrets in a hierarchical threshold linear secret sharing scheme (LSSS). Starting with known ideal constructions, we then propose a modified scheme with improved multiplication ...
متن کاملOn Multiplicative Linear Secret Sharing Schemes
We consider both information-theoretic and cryptographic settings for Multi-Party Computation (MPC), based on the underlying linear secret sharing scheme. Our goal is to study the Monotone Span Program (MSP), that is the result of local multiplication of shares distributed by two given MSPs as well as the access structure that this resulting MSP computes. First, we expand the construction propo...
متن کاملStrongly Multiplicative and 3-Multiplicative Linear Secret Sharing Schemes
Strongly multiplicative linear secret sharing schemes (LSSS) have been a powerful tool for constructing secure multi-party computation protocols. However, it remains open whether or not there exist efficient constructions of strongly multiplicative LSSS from general LSSS. In this paper, we propose the new concept of 3-multiplicative LSSS, and establish its relationship with strongly multiplicat...
متن کاملOn Multiplicative Secret Sharing Schemes Realizing Graph Access Structures
In this paper we consider graph access structures and we show that such an access structure can be realized by a (strongly) multiplicative monotone span program if and only if the privacy structure contains at least three (resp. four) maximal sets. Thus, we obtain a new family of access structures with an explicit construction that is both ideal and strongly multiplicative. Until now only three...
