Untangle: A Principled Framework to Design Low-Leakage, High-Performance Dynamic Partitioning Schemes
Zirui Neil Zhao, Adam Morrison, Christopher W. Fletcher, Josep Torrellas · 2023
Partitioning a hardware structure dynamically among multiple security domains leaks some information but can deliver high performance. To understand the performance-security tradeoff of dynamic partitioning, it would be useful to formally quantify the leakage of these schemes. Unfortunately, this is hard, as what partition resizing decisions are made and when they are made are entangled.
