Side-channel attacks have become a severe threat to the confidentiality of computer
applications and systems. One popular type of such attacks is the microarchitectural attack …

We present an effective implementation of the Prime+ Probe side-channel attack against the
last-level cache. We measure the capacity of the covert channel the attack creates and …

The presence of large numbers of security vulnerabilities in popular feature-rich commodity
operating systems has inspired a long line of work on excluding these operating systems …

Microarchitectural timing channels expose hidden hardware states though timing. We survey
recent attacks that exploit microarchitectural features in shared hardware, especially as they …

In the last 10 years, cache attacks on Intel x86 CPUs have gained increasing attention
among the scientific community and powerful techniques to exploit cache side channels …

Cache side channel attacks are serious threats to multi-tenant public cloud platforms. Past
work showed how secret information in one virtual machine (VM) can be extracted by …

Simultaneous Multithreading (SMT) architectures are attractive targets for side-channel
enabled attackers, with their inherently broader attack surface that exposes more per …

The scatter–gather technique is a commonly implemented approach to prevent cache-based
timing attacks. In this paper, we show that scatter–gather is not constant time. We implement …

Privacy protection is an essential part of information security. The use of shared resources
demands more privacy and security protection, especially in cloud computing environments …

We are witnessing a confluence between applied cryptography and secure hardware
systems in enabling secure cloud computing. On one hand, work in applied cryptography …
