| Abstract(in English) | Secret sharing is a basic primitive for cryptographic protocols. Since Shamir showed his famous threshold scheme, many secret sharing schemes have been proposed so far. Most of the existing secret sharing schemes distribute partial information about a single secret to participants with no specific structure. In this paper we present novel schemes for sharing multilevel secrets among groups using concatenation of Reed-Solomon codes. In the proposed schemes a lower level secret can be reconstructed by a smaller number of groups, while reconstructing a higher level secret needs the collaboration of a larger number of groups. |
