Canonical title: Understanding and Mitigating Covert Channel and Side Channel Vulnerabilities Introduced by RowHammer Defenses | |||
Question: Do RowHammer defenses themselves create exploitable timing channels? | |||
Context: Defense-induced refresh, throttling, or tracking alters memory timing in ways visible across protection boundaries. | |||
Method: LeakyHammer constructs covert/side channels from defense behavior, demonstrates website fingerprinting, and evaluates three mitigations. | |||
Evaluation: workloads=two constructed channels and website-fingerprinting attack; baselines=RowHammer defenses with and without three mitigations; metrics=channel bandwidth, attack success, mitigation overhead; results=41.9 and 54.0 Kbps in latest version | |||
Interpretation: A defense can close an integrity attack while opening an information-flow channel through its observable actions. | |||
Reusable lesson: Evaluate security mechanisms for timing/noninterference, not only for prevention efficacy. | |||
Applicability: DRAM systems deploying stateful or throttling-based RowHammer defenses. | |||
Limits: Channel feasibility and mitigation overhead depend on the specific defense and platform; arXiv versions report different older rates.</nowiki> | |||
