Partitioned Tags, Shared Data: Reconciling Strict Cache Isolation with Write-Shared Coherence
Kartik Ramkrishnan, Stephen McCamant, Antonia Zhai +1
Cache partitioning is among the strongest structural defenses against eviction-based cache side channels, yet a decade-old design issue has blocked its widespread deployment in sec…
Supporting Secured Integration of Microarchitectural Defenses
Kartik Ramkrishnan, Stephen McCamant, Antonia Zhai +1
There has been a plethora of microarchitectural-level attacks leading to many proposed countermeasures. This has created an unexpected and unaddressed security issue where naive in…
Shield Bash: Abusing Defensive Coherence State Retrieval to Break Timing Obfuscation
Kartik Ramkrishnan, Antonia Zhai, Stephen McCamant +1
Microarchitectural attacks are a significant concern, leading to many hardware-based defense proposals. However, different defenses target different classes of attacks, and their i…
New Attacks and Defenses for Randomized Caches
Kartik Ramkrishnan, Antonia Zhai, Stephen McCamant +1
The last level cache is vulnerable to timing based side channel attacks because it is shared by the attacker and the victim processes even if they are located on different cores. T…
