A Touch of Evil: High-Assurance Cryptographic Hardware from Untrusted Components [PDF]
, 2017 The semiconductor industry is fully globalized and integrated circuits (ICs) are commonly defined, designed and fabricated in different premises across the world. This reduces production costs, but also exposes ICs to supply chain attacks, where insiders

An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems
International Economic Review, EarlyView.ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.

Securing End‐To‐End Encrypted File Sharing Services With the Messaging Layer Security Protocol
Concurrency and Computation: Practice and Experience, Volume 37, Issue 27-28, 25 December 2025.ABSTRACT Secure file sharing is essential in today's digital environment, yet many systems remain vulnerable: if an attacker steals client keys, they can often decrypt both past and future content. To address this challenge, we propose a novel file‐sharing architecture that strengthens post‐compromise security while remaining practical.
