Leakage contracts have recently been proposed as a new security abstraction at the
Instruction Set Architecture (ISA) level. Leakage contracts aim to capture the information that …

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

Microarchitectural attacks compromise security by exploiting software-visible artifacts of
microarchitectural optimizations such as caches and speculative execution. Defending …

A new class of vulnerabilities related to speculative and out-of-order execution, fault-
injection, and microarchitectural side channels rose to attention in 2018. The techniques …

Recent research has unveiled numerous cache-timing side-channel attacks exploiting the
side effects of fine-grained cache features, such as coherence protocol and prefetch, among …

Transient execution vulnerabilities have affected CPUs for the better part of the decade, yet,
we are still missing methods to efficiently uncover them at the design stage. Existing …

The increasing complexity of modern processor and IP designs presents significant
challenges in identifying and mitigating hardware flaws early in the IC design cycle …

Modern processor advancements have introduced security risks, particularly in the form of
microarchitectural timing attacks. High-profile attacks such as Meltdown and Spectre have …

Many mitigations have been proposed and implemented for many variants of the transient
execution vulnerabilities, and while the Meltdown-type exception-based transient execution …
