Trusted execution environments, and particularly the Software Guard eXtensions (SGX)
included in recent Intel x86 processors, gained significant traction in recent years. A long …

In early 2018, Meltdown first showed how to read arbitrary kernel memory from user space
by exploiting side-effects from transient instructions. While this attack has been mitigated …

This paper presents a comprehensive survey on the development of Intel SGX (software
guard extensions) processors and its applications. With the advent of SGX in 2013 and its …

Research on transient execution attacks including Spectre and Meltdown showed that
exception or branch misprediction events might leave secret-dependent traces in the CPU's …

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

Microarchitectural vulnerabilities, such as Meltdown and Spectre, exploit subtle
microarchitecture state to steal the user's secret data and even compromise the operating …

Speculative execution is an optimization technique that has been part of CPUs for over a
decade. It predicts the outcome and target of branch instructions to avoid stalling the …

All Spectre attacks so far required local code execution. We present the first fully remote
Spectre attack. For this purpose, we demonstrate the first access-driven remote Evict+ …

When applying machine learning to sensitive data, one has to find a balance between
accuracy, information security, and computational-complexity. Recent studies combined …

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 …
