Quantum-Augmented Networking Bolsters Microgrid Cybersecurity Against Traffic Analysis and Spoofing
Proposes QuAM framework integrating quantum secure networking, anonymous notifications, and random number generation to enhance microgrid integrity, confidentiality, and privacy for SMR-powered distributed grids. Simulates classical traffic analysis and priority-action spoofing attacks that deanonym…
Unified Security Framework Enables Rigorous Analysis of Quantum Distance-Bounding Protocols
Authors introduce a reusable game-based security framework for quantum distance-bounding (QDB) protocols, standardizing system assumptions, quantum adversary models, and fraud experiments (distance-, mafia-, terrorist-fraud) with i.i.d. depolarizing noise. Applied to a published QDB protocol, it pro…
Reduced Quantum Resources Threaten Cryptocurrency Elliptic Curve Cryptography
A new whitepaper reveals that future quantum computers may break elliptic curve cryptography (ECC) with significantly fewer qubits and gates than previously estimated. This poses a threat to cryptocurrencies and other systems reliant on ECC. The research advocates for a transition to post-quantum cr…
Quantum Computing Threatens Current Cryptocurrencies
Quantum computers capable of executing Shor's algorithm pose an imminent threat to elliptic curve cryptography, the foundation of modern blockchain security. This vulnerability allows for "on-spend" attacks on cryptocurrency transactions, particularly impacting fast-clock quantum architectures. The …
