arXiv:2609.03893v1 Announce Type: new Abstract: Microarchitectural side-channel research has grown at an exceptional pace in recent years, increasing the need for rigorous and meaningful benchmarking. Early attack papers typically relied on indirect proxies, such as covert-channel bandwidth or key-recovery on naive AES and RSA implementations, setting de facto standards that many subsequent works continued to replicate, sometimes by directly comparing against raw numbers from prior work. While

Editorial Analysis

Why it matters

Unreliable side-channel benchmarks can lead enterprises to misjudge hardware risk exposure; better methodology strengthens the evidence base for procurement and mitigation decisions.
