Linear Threshold Multisecret Sharing Schemes
In a multisecret sharing scheme, several secret values are distributed among a set of n users, and each secret may have a different associated access structure. We consider here information-theoretic secure schemes with multithreshold access structures. Namely, for every subset P of k users there is a secret key that can only be computed when at least t of them put together their secret informa...
متن کاملMultisecret Threshold Schemes
A threshold scheme is a system that protects a secret (key) among a group of participants in such a way that it can only be reconstructed from the joint information held by some predetermined number of these participants. In this paper we extend this problem to one where there is more than one secret that participants can reconstruct using the information that they hold. In particular we consid...
متن کاملLinear Multisecret-Sharing Schemes and Error-Correcting Codes
In this paper a characterization of the general relation between linear multisecret-sharing schemes and error-correcting codes is presented. A bridge between linear multisecret-sharing threshold schemes and maximum distance separable codes is set up. The information hierarchy of linear multisecret-sharing schemes is also established. By making use of the bridge several linear multisecret-sharin...
متن کاملGraphic Multisecret Sharing Schemes with One-Dimensional Cellular Automata
A multi-secret sharing scheme, which is based on one-dimensional reversible cellular automata with memory, allowing any member of a set of participants to share a secret color image with the rest of participants is presented. Moreover, it is also explained that with this scheme, any participant is able to recover all the secret color images if and only if the whole set of participants pools the...
متن کاملPractical Threshold Signatures with Linear Secret Sharing Schemes
Function sharing deals with the problem of distribution of the computation of a function (such as decryption or signature) among several parties. The necessary values for the computation are distributed to the participating parties using a secret sharing scheme (SSS). Several function sharing schemes have been proposed in the literature, with most of them using Shamir secret sharing as the unde...
