"They don't care about this": A Systematic Study of TEE Build Reproducibility in the Wild
Annika Wilde, Marco Gutfleisch, Felix Reichmann +4
Trusted Execution Environments (TEEs) have become a cornerstone of modern cloud computing, providing strong confidentiality and integrity guarantees for both code and data. A criti…
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…
Shesha: Multi-head Microarchitectural Leakage Discovery in new-generation Intel Processors
Anirban Chakraborty, Nimish Mishra, Debdeep Mukhopadhyay
Transient execution attacks have been one of the widely explored microarchitectural side channels since the discovery of Spectre and Meltdown. However, much of the research has bee…
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…
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…
Adversarial Attacks and Defences: A Survey
Anirban Chakraborty, Manaar Alam, Vishal Dey +2
Deep learning has emerged as a strong and efficient framework that can be applied to a broad spectrum of complex learning problems which were difficult to solve using the tradition…
