Microarchitectural vulnerabilities, such as Meltdown and Spectre, exploit subtle
microarchitecture state to steal the user's secret data and even compromise the operating …

Shared caches have been a prime target for mounting crossprocess/core side-channel
attacks. Fundamentally, these attacks require a mechanism to accurately observe changes …

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 …

Microarchitectural attacks threaten the security of computer systems even in the absence of
software vulnerabilities. Such attacks are well explored on x86 and ARM CPUs, with a wide …

While extensive research has been conducted on CPU cache side-channel attacks, the
landscape of similar studies on modern GPUs remains largely uncharted. In this paper, we …

A large body of work has demonstrated attacks that rely on the difference between CPUs'
nominal instruction set architectures and their actual (microarchitectural) implementations …

Covert channels and side channels bypass architectural security boundaries. Numerous
works have studied covert channels and side channels in software and hardware. Thus …

Trusted Execution Environments are a promising solution for solving the data privacy and
trust issues introduced by cloud computing. As a result, all major CPU vendors integrated …

Memory coloring is a software-based technique to ensure microarchitectural isolation
between trust domains sharing a CPU. Prior coloring schemes target individual …

Interrupts are fundamental for inter-process and cross-core communication in modern
systems. Controlling these communication mechanisms historically requires switches into …
