Boolean Operation Based Visual Cryptography
IEEE Access, 2019 A ( $k$ , $n$ )-Traditional Visual Cryptographic Scheme (VCS) based on basis matrices encoded a secret image into $n$ shadow images distributed among $n$ participants.

A Combinatorial Approach to Threshold Schemes [PDF]
SIAM Journal on Discrete Mathematics, 1988 We investigate the combinatorial properties of threshold schemes. Informally, a (t,w)-threshold scheme is a way of distributing partial information (shadows) to w participants, so that any t of them can easily calculate a key, but no subset of fewer than t participants can determine the key.

Reaching consensus for membership dynamic in secret sharing and its application to cross-chain
High-Confidence Computing, 2023 The communication efficiency optimization, censorship resilience, and generation of shared randomness are inseparable from the threshold cryptography in the existing Byzantine Fault Tolerant (BFT) consensus.

A distributed key establishment scheme for wireless mesh networks using identity-based cryptography [PDF]
, 2010 In this paper, we propose a secure and efficient key establishment scheme designed with respect to the unique requirements of Wireless Mesh Networks. Our security model is based on Identity-based key establishment scheme without the utilization of a ...

Bounding inconsistency using a novel threshold metric for dead reckoning update packet generation [PDF]
, 2008 Human-to-human interaction across distributed applications requires that sufficient consistency be maintained among participants in the face of network characteristics such as latency and limited bandwidth.

Threshold Lattice-Based Signature Scheme for Authentication by Wearable Devices
Cryptography, 2023 This paper presents a new threshold signature scheme based on Damgaard’s work. The proposed scheme allows for changing the message signature threshold, thereby improving the flexibility of the original Damgaard scheme.

QPSK coherent state discrimination via a hybrid receiver [PDF]
, 2012 We propose and experimentally demonstrate a near-optimal discrimination scheme for the quadrature phase shift keying protocol (QPSK). We show in theory that the performance of our hybrid scheme is superior to the standard scheme - heterodyne detection ...

User-Centric Interference Nulling in Downlink Multi-Antenna Heterogeneous Networks
, 2016 In heterogeneous networks (HetNets), strong interference due to spectrum reuse affects each user's signal-to-interference ratio (SIR), and hence is one limiting factor of network performance. In this paper, we propose a user-centric interference nulling (

, 1999 We investigate the concept of quantum secret sharing. In a ((k,n)) threshold scheme, a secret quantum state is divided into n shares such that any k of those shares can be used to reconstruct the secret, but any set of k-1 or fewer shares contains ...
