Addendum: Systematic Evaluation of Randomized Cache Designs against Cache Occupancy
Anirban Chakraborty, Nimish Mishra, Sayandeep Saha +2
In the main text published at USENIX Security 2025, we presented a systematic analysis of the role of cache occupancy in the design considerations for randomized caches (from the p…
"Energon": Unveiling Transformers from GPU Power and Thermal Side-Channels
Arunava Chaudhuri, Shubhi Shukla, Sarani Bhattacharya +1
Transformers have become the backbone of many Machine Learning (ML) applications, including language translation, summarization, and computer vision. As these models are increasing…
A practical key-recovery attack on LWE-based key-encapsulation mechanism schemes using Rowhammer
Puja Mondal, Suparna Kundu, Sarani Bhattacharya +2
Physical attacks are serious threats to cryptosystems deployed in the real world. In this work, we propose a microarchitectural end-to-end attack methodology on generic lattice-bas…
Systematic Evaluation of Randomized Cache Designs against Cache Occupancy
Anirban Chakraborty, Nimish Mishra, Sayandeep Saha +2
Randomizing the address-to-set mapping and partitioning of the cache has been shown to be an effective mechanism in designing secured caches. Several designs have been proposed on…
A short note on the paper `Are Randomized Caches Really Random?'
Anirban Chakraborty, Sarani Bhattacharya, Sayandeep Saha +1
In this paper, we analyse the results and claims presented in the paper \emph{`Are Randomized Caches Truly Random? Formal Analysis of Randomized Partitioned Caches'}, presented at…
On the Evaluation of User Privacy in Deep Neural Networks using Timing Side Channel
Shubhi Shukla, Manaar Alam, Sarani Bhattacharya +2
Recent Deep Learning (DL) advancements in solving complex real-world tasks have led to its widespread adoption in practical applications. However, this opportunity comes with signi…
RAPPER: Ransomware Prevention via Performance Counters
Manaar Alam, Sayan Sinha, Sarani Bhattacharya +3
Ransomware can produce direct and controllable economic loss, which makes it one of the most prominent threats in cyber security. As per the latest statistics, more than half of ma…
ExplFrame: Exploiting Page Frame Cache for Fault Analysis of Block Ciphers
Anirban Chakraborty, Sarani Bhattacharya, Sayandeep Saha +1
Page Frame Cache (PFC) is a purely software cache, present in modern Linux based operating systems (OS), which stores the page frames that are recently being released by the proces…
