High performance logistic regression for privacy-preserving genome analysis

BMC Medical Genomics, 2021
Background In biomedical applications, valuable data is often split between owners who cannot openly share the data because of privacy regulations and concerns.

Wiretap codes for secure multi-party computation

2014 IEEE Globecom Workshops (GC Wkshps), 2014
In this paper, we propose a new secret sharing scheme for secure multi-party computation. We present a general framework that allows us to construct efficient secret sharing schemes from channel coding techniques for the wiretap channel. The resulting schemes can be employed to securely calculate linear functions of data that are distributed in a ...

Private feasible solution determination

IET Information Security, 2021
Applying secure multi‐party computation (SMC) to implement secure linear programming is an important problem of SMC. Private feasible solution determination means that one of the participants has a private value and the other participants have some ...

In Situ Integrated Titanium Oxide Synaptic Phototransistor Enabling Multimodal Plasticity and Noise‐Robust Selective Attention

Advanced Materials Technologies, EarlyView.
An in situ integrated TiO2/SiOx/Al2O3 synaptic phototransistor couples ultraviolet and electrical stimuli within a scalable, CMOS‐compatible oxide stack. Multimodal plasticity, spike‐timing‐dependent learning, and bee‐inspired associative conditioning are achieved through trap‐mediated temporal dynamics.

All-or-nothing oblivious transfer based on the quantum one-way function

Frontiers in Physics, 2022
Oblivious transfer (OT) is one of the keystones of secure multi-party computation. It is generally believed that unconditionally secure OT is impossible.

Selenium Nanoparticles Selectively Target KRAS G13D to Inhibit Colorectal Cancer

Advanced Science, EarlyView.
The mechanisms of SeNPs therapy in cancer treatment, encompass three parallel actions: (1) seleno‐amino acids, key metabolites, upregulate GPX2 expression, thereby inhibiting tumor metastasis via the GPX2‐HIF1α‐VEGF signaling pathway; (2) selenite (SeO32−), an inorganic metabolite, forms hydrogen bonds with amino acid residues 13–17 of the KRAS G13D ...

Privacy-preserving multi-party data joint analysis scheme based on multiset operations in smart contracts

Journal of King Saud University: Computer and Information Sciences
With the advancement of blockchain technology, smart contracts are increasingly applied in finance, supply chain, healthcare, and other domains. However, the demand for multi-party data joint analysis within these contracts faces challenges of privacy ...

Secure Multi-Party Computation with Identifiable Abort [PDF]

, 2014
Protocols for secure multi-party computation (MPC) that resist a dishonest majority are susceptible to “denial of service” attacks, allowing even a single malicious party to force the protocol to abort. In this work, we initiate a systematic study of the more robust notion of security with identifiable abort, which leverages the effect of an abort by ...

Secure Multi-party Computation with Legally-Enforceable Fairness

International Journal of Information Security, 2023
AbstractFairness is a security notion of secure computation and cannot always be achieved if an adversary corrupts a majority of parties in standard settings. Lindell (CT-RSA 2008) showed that imposing a monetary penalty on an adversary can circumvent the impossibility.
