CLIP: Client-Side Invariant Pruning for Mitigating Stragglers in Secure Federated Learning
Anthony DiMaggio, Raghav Sharma, Gururaj Saileshwar
Secure federated learning (FL) preserves data privacy during distributed model training. However, deploying such frameworks across heterogeneous devices results in performance bott…
Yet Another Mirage of Breaking MIRAGE: Debunking Occupancy-based Side-Channel Attacks on Fully Associative Randomized Caches
Chris Cao, Gururaj Saileshwar
Recent work presented at USENIX Security 2025 (SEC'25) claims that occupancy-based attacks can recover AES keys from the MIRAGE randomized cache. In this paper, we examine these cl…
GPUHammer: Rowhammer Attacks on GPU Memories are Practical
Chris S. Lin, Joyce Qu, Gururaj Saileshwar
Rowhammer is a read disturbance vulnerability in modern DRAM that causes bit-flips, compromising security and reliability. While extensively studied on Intel and AMD CPUs with DDR…
CnC-PRAC: Coalesce, not Cache, Per Row Activation Counts for an Efficient in-DRAM Rowhammer Mitigation
Chris S. Lin, Jeonghyun Woo, Prashant J. Nair +1
JEDEC has introduced the Per Row Activation Counting (PRAC) framework for DDR5 and future DRAMs to enable precise counting of DRAM row activations using per-row activation counts.…
When Mitigations Backfire: Timing Channel Attacks and Defense for PRAC-Based RowHammer Mitigations
Jeonghyun Woo, Joyce Qu, Gururaj Saileshwar +1
Per Row Activation Counting (PRAC) has emerged as a robust framework for mitigating RowHammer (RH) vulnerabilities in modern DRAM systems. However, we uncover a critical vulnerabil…
AMuLeT: Automated Design-Time Testing of Secure Speculation Countermeasures
Bo Fu, Leo Tenenbaum, David Adler +7
In recent years, several hardware-based countermeasures proposed to mitigate Spectre attacks have been shown to be insecure. To enable the development of effective secure speculati…
QPRAC: Towards Secure and Practical PRAC-based Rowhammer Mitigation using Priority Queues
Jeonghyun Woo, Chris S. Lin, Prashant J. Nair +2
JEDEC has introduced the Per Row Activation Counting (PRAC) framework for DDR5 and future DRAMs to enable precise counting of DRAM row activations. PRAC enables a holistic mitigati…
