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.

Efficient rare event simulation for failure problems in random media [PDF]
, 2014 In this paper we study rare events associated to solutions of elliptic partial differential equations with spatially varying random coefficients. The random coefficients follow the lognormal distribution, which is determined by a Gaussian process.

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.

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-Based Fast Successive-Cancellation Decoding of Polar Codes [PDF]
, 2020 Fast SC decoding overcomes the latency caused by the serial nature of the SC decoding by identifying new nodes in the upper levels of the SC decoding tree and implementing their fast parallel decoders.

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 ...

Verifiable Threshold Quantum State Sharing Scheme
IEEE Access, 2018 Quantum state sharing (QSTS) is a hot topic in quantum cryptography. However, majority of the current structures cannot resist the participant's fraud well during the initial state reconstruction phase.

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.
