Secret shares to protect health records in Cloud-based infrastructures

2015

Increasingly health records are stored in cloud-based systems, and often protected by a private key. Unfortunately the loss of this key can cause large-scale data loss. This paper outlines a novel Cloud-based architecture (SECRET) which …

Seamless Cryptographic Key Generation via Off-the-Shelf Telecommunication Components for End-to-End Data Encryption

2017

Quantum key distribution (QKD) systems have already attained much attention for providing end-to-end data encryption to the subscribers. However, it is very important that the QKD infrastructure is compatible with the already existing telecommunication networks …

Experimental High Speed Data Encryption via SDM-CV-QKD Signaling for High-Capacity Access Network

2018 · Advanced Photonics 2018 (BGPP, IPR, NP, NOMA, Sensors, Networks, SPPCom, SOF)

We report a high capacity Quantum-to-the-Home (QTTH) network in a spatial-division-multiplexing (SDM) network utilizing 7-core multicore fiber (MCF). Aggregate secure key rates of 33.6 Mbit/s over 9.8 km of fiber are the actual state-of-the-art.

An Omnidirectional Approach to Touch-based Continuous Authentication

2023 · arXiv (Cornell University)

This paper focuses on how touch interactions on smartphones can provide a continuous user authentication service through behaviour captured by a touchscreen. While efforts are made to advance touch-based behavioural authentication, researchers often focus on …

A Framework for the Security and Privacy of Biometric System Constructions under Defined Computational Assumptions

2024 · arXiv (Cornell University)

Biometric systems, while offering convenient authentication, often fall short in providing rigorous security assurances. A primary reason is the ad-hoc design of protocols and components, which hinders the establishment of comprehensive security proofs. This paper …
