Secret-Key Generation in Many-to-One Networks: An Integrated Game-Theoretic and Information-Theoretic Approach

Abstract This paper considers secret-key generation between several agents and a base station that observe independent and identically distributed realizations of correlated random variables. Each agent wishes to generate the longest possible individual key with the base station by means of public communication. All keys must be jointly kept secret from all external entities. Also each agent ha...

Non-Interactive and Information-Theoretic Secure Publicly Verifiable Secret Sharing

A publicly verifiable secret sharing scheme is more applicable than a verifiable secret sharing because of the property that the validity of the shares distributed by the dealer can be verified by any party. In this paper, we construct a non-interactive and informationtheoretic publicly verifiable secret sharing by a computationally binding and unconditionally hiding commitment scheme and zero-...

Timed-Release Secret Sharing Schemes with Information Theoretic Security

In modern cryptography, the secret sharing scheme is an important cryptographic primitive and it is used in various situations. In this paper, a timed-release secret sharing scheme (TR-SS) with information-theoretic security is first studied. TRSS is a secret sharing scheme with the property that participants more than a threshold number can reconstruct a secret by using their shares only when ...
