Information flow tracking (IFT) is a fundamental computer security technique used to
understand how information moves through a computing system. Hardware IFT techniques …

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 …

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

Speculative execution attacks present an enormous security threat, capable of reading
arbitrary program data under malicious speculation, and later exfiltrating that data over …

Users of modern data-processing services such as tax preparation or genomic screening
are forced to trust them with data that the users wish to keep secret. Ryoan1 protects secret …

Information security can be compromised by leakage via low-level hardware features. One
recently prominent example is cache probing attacks, which rely on timing channels created …

Blocking microarchitectural (digital) side channels is one of the most pressing challenges in
hardware security today. Recently, there has been a surge of effort that attempts to block …

Microarchitectural attacks have plunged Computer Architecture into a security crisis. Yet, as
the slowing of Moore's law justifies the use of ever more exotic microarchitecture, it is likely …

Privacy and integrity are important security concerns. These concerns are addressed by
controlling information flow, ie, restricting how information can flow through a system. Most …

As multicore processors find increasing adoption in domains such as aerospace and
medical devices where failures have the potential to be catastrophic, strong performance …
