متن کاملMitigating Node Capture Attack in Random Key Distribution Schemes through Key Deletion
Random Key Distribution (RKD) schemes have been widely accepted to enable low-cost secure communications in Wireless Sensor Networks (WSNs). However, efficiency of secure link establishment comes with the risk of compromised communications between benign nodes by adversaries who physically capture sensor nodes. The challenge is to enhance resilience of WSN against node capture, while maintainin...
متن کاملPractical round-robin differential phase-shift quantum key distribution.
Recently, a novel protocol named round-robin differential phase-shift (RRDPS) quantum key distribution [Nature 509, 475(2014)] has been proposed. It can estimate information leakage without monitoring bit error rate. In this paper, we study the performance of RRDPS using heralded single photon source (HSPS) without and with decoy-state method, then compare it with the performance of weak cohere...
متن کاملSecurity of practical phase-coding quantum key distribution
Security proof of practical quantum key distribution (QKD) has attracted a lot of attentions in recent years. Most of real-life QKD implementations are based on phase-coding BB84 protocol, which usually uses Unbalanced Mach-Zehnder Interferometer (UMZI) as the information coder and decoder. However, the long arm and short arm of UMZI will introduce different loss in practical experimental reali...
متن کاملSaturation Attack on Continuous-Variable Quantum Key Distribution System
Introduction Quantum key distribution (QKD) [1] enables two remote parties Alice and Bob to share common secure keys which are unknown to a potential eavesdropper. Unconditional security of QKD is based on the fundamental laws of quantum mechanics, but in reality, securities of practical QKD systems could be jeopardized by physical implementations. In discretevariable (DV) QKD system, due to de...
