Almost-perfect secret sharing [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 Splitting a secret s between several participants, we generate (for each value of s) shares for all participants. The goal: authorized groups of participants should be able to reconstruct the secret but forbidden ones get no information about it. In this paper we introduce several notions of non- perfect secret sharing, where some small information ...

Secret Sharing LDPC Codes for the BPSK-constrained Gaussian Wiretap Channel
, 2011 The problem of secret sharing over the Gaussian wiretap channel is considered. A source and a destination intend to share secret information over a Gaussian channel in the presence of a wiretapper who observes the transmission through another Gaussian ...

Information Privacy Protection Based on Verifiable (t, n)-Threshold Multi-Secret Sharing Scheme
IEEE Access, 2020 General secret sharing schemes comprise a secret dealer and a number of participants. The dealer can randomly generate a secret and then distribute shares of the secret to the participants.

Multilevel Threshold Secret and Function Sharing based on the Chinese Remainder Theorem [PDF]
, 2016 A recent work of Harn and Fuyou presents the first multilevel (disjunctive) threshold secret sharing scheme based on the Chinese Remainder Theorem. In this work, we first show that the proposed method is not secure and also fails to work with a certain ...

Efficient and Lossless Polynomial-Based Secret Image Sharing for Color Images
IEEE Access, 2019 In today's era of developed network, it is particularly important to ensure the security of information. Secret image sharing is a kind of secret information protection technology with loss tolerance by sharing a secret image to a number of shadow images.

Controlled Quantum Secret Sharing
, 2006 We present a new protocol in which a secret multiqubit quantum state $\ket{\Psi}$ is shared by $n$ players and $m$ controllers, where $\ket{\Psi}$ is the encoding state of a quantum secret sharing scheme.

Key distribution and recovery algorithm based on Shamir's secret sharing
Tongxin xuebao, 2015 In Shamir's secret sharing scheme, the dealer divided the secret s into n shadows and distributed it to share-holders in such a way that any t or more than t shadows can recover this secret, while fewer than t shadows cannot obtain any information about ...

Nonlinear Secret Image Sharing Scheme
The Scientific World Journal, 2014 Over the past decade, most of secret image sharing schemes have been proposed by using Shamir's technique. It is based on a linear combination polynomial arithmetic.
