We introduce Downfall attacks, new transient execution attacks that undermine the security
of computers running everywhere across the internet. We exploit the gather instruction on …

We study microarchitectural side-channel attacks and defenses on non-volatile RAM
(NVRAM) DIMMs. In this study, we first perform reverse-engineering of NVRAMs as …

Over the past few years, the high-end CPU market is undergoing a transformational change.
Moving away from using x86 as the sole architecture for high performance devices, we have …

BunnyHop: Exploiting the Instruction Prefetcher Page 1 This paper is included in the
Proceedings of the 32nd USENIX Security Symposium. August 9–11, 2023 • Anaheim, CA …

Research into processor-based side-channels has seen both a large number and a large
variety of disclosed vulnerabilities that can leak critical, private data to malicious attackers …

How will future microarchitectures impact the security of existing cryptographic
implementations? As we cannot keep reducing the size of transistors, chip vendors have …

As modern SoC architectures incorporate many complex/heterogeneous intellectual
properties (IPs), the protection of security assets has become imperative, and the number of …

Spectre and Meltdown have pushed the research community toward an otherwise-
unavailable understanding of the security implications of processors' microarchitecture …

Cryptography secures our online interactions, transactions, and trust. To achieve this goal,
not only do the cryptographic primitives and protocols need to be secure in theory, they also …

The past decade has seen a deluge of microarchitectural side channels stemming from a
variety of hardware structures (the cache, branch predictor, execution ports, the TLB …
