In this paper we revisit the Spectre v1 vulnerability and software-only countermeasures.
Specifically, we systematically investigate the performance penalty and security properties of …

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 …

For over two decades, cache attacks have been shown to pose a significant risk to the
security of computer systems. In particular, a large number of works show that cache attacks …

Browser fingerprinting is often associated with cross-site user tracking, a practice that many
browsers (eg, Safari, Brave, Edge, Firefox, and Chrome) want to block. However, less is …

In the quest for efficiency and performance, edge-computing providers replace process
isolation with sandboxes, to support a high number of tenants per machine. While secure …

Microarchitectural attacks typically rely on precise timing sources to uncover short-lived
secret-dependent activity in the processor. In response, many browsers and even CPU …

Type confusion bugs are a common source of security problems whenever software makes
use of type hierarchies, as an inadvertent downcast to an incompatible type is hard to detect …

Apple silicon is the proprietary ARM-based processor that powers the mainstream of Apple
devices. The move to this proprietary architecture presents unique challenges in addressing …

ARM Memory Tagging Extension (MTE) is a new hardware feature introduced in ARMv8. 5-
A architecture, aiming to detect memory corruption vulnerabilities. The low overhead of MTE …

Sharing microarchitectural components between co-resident programs leads to potential
information leaks, with devastating implications on security. Over the last decade, multiple …
