Over the last two decades, side and covert channel research has shown a variety of ways of
exfiltrating information for a computer system. Processor microarchitectural timing-based …

The recent Spectre attacks exploit speculative execution, a pervasively used feature of
modern microprocessors, to allow the exfiltration of sensitive data across protection …

Research on cache attacks has shown that CPU caches leak significant information.
Proposed detection mechanisms assume that all cache attacks cause more cache hits and …

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

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 …

A timing channel is a communication channel that can transfer information to a
receiver/decoder by modulating the timing behavior of an entity. Examples of this entity …

Side-channel attacks monitor some aspect of a computer system's behavior to infer the
values of secret data. Numerous side-channels have been exploited, including those that …

Correctly functioning caches have been shown to leak critical secrets like encryption keys,
through various types of cache side-channel attacks. This nullifies the security provided by …

Cloud services are rapidly gaining adoption due to the promises of cost efficiency,
availability, and on-demand scaling. To achieve these promises, cloud providers share …

Privacy and information security in general are major concerns that impede enterprise
adaptation of shared or public cloud computing. Specifically, the concern of virtual machine …
