Information-theoretically Secure Timed-release Secret Sharing Schemes

Information-theoretically Secure Strong Verifiable Secret Sharing

In a (t,n) secret sharing scheme, a mutually trusted dealer divides a secret into n shares in such a way that any t or more than t shares can reconstruct the secret, but fewer than t shares cannot reconstruct the secret. When there is no mutually trusted dealer, a (n,t,n) secret sharing scheme can be used to set up a (t,n) secret sharing because each shareholder also acts as a dealer to decide ...

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 ...

Computationally secure multiple secret sharing: models, schemes, and formal security analysis

A multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants. in such a way a multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants, such that any authorized subset of participants can reconstruct the secrets. Up to now, existing MSSs either require too long shares for participants to be perfect secur...
