Last week we announced our public side-channel mitigation test and benchmarking lab in light of the publication of the TAA variant of ZombieLoad. This new lab will enable us to evaluate new side-channel attacks and new mitigations and answer questions such as:
- Do the mitigations work?
- How much performance does each individual mitigation cost?
- How much performance do the combined mitigations cost?
- Are there platforms that stand out in performance cost?
In this article we will take a closer look at these questions with a comparison of a Linux kernel compile benchmark on different hardware plattforms with different Linux kernels.read more
