Trusted execution environment (TEE) offers data protection against malicious system
software. However, the TEE (eg, Intel SGX) threat model exacerbates information leakage as …

Modern CPUs dynamically scale voltage and frequency for efficiency. However, too low
voltages can result in security-critical errors. Hence, vendors use a generous safety margin …

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 …

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

CPU caches are among the most widely studied side-channel targets, with Prime+ Probe
and Flush+ Reload being the most prominent techniques. These generic cache attack …

Over the past few years, several research groups have introduced innovative hardware
designs for Trusted Execution Environments (TEEs), aiming to secure applications against …

Abstract Acoustic Side-Channel Attacks (ASCAs) extract sensitive information by using
audio emitted from a computing devices and their peripherals. Attacks targeting keyboards …

Energy consumption trends from reporting interfaces like Running Average Power Limit
(RAPL) can be leveraged by remote adversaries to mount software counterparts of power …

Garbled circuits (GC) are a secure multiparty computation protocol that enables two parties
to jointly compute a function using their private data without revealing it to each other. While …

Side-channel information consists of side effects of computation that range from
microarchitectural to physical phenomena. Empirical studies have demonstrated the …
