The world is undergoing an unprecedented technological transformation, evolving into a
state where ubiquitous Internet-enabled “things” will be able to generate and share large …

Trusted Execution Environments (TEEs) have been widely used in many security-critical
applications. The popularity of TEEs derives from its high security and trustworthiness …

Modern processors use branch prediction and speculative execution to maximize
performance. For example, if the destination of a branch depends on a memory value that is …

Meltdown: reading kernel memory from user space Page 1 46 COMMUNICATIONS OF THE

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 security of computer systems fundamentally relies on memory isolation, eg, kernel
address ranges are marked as non-accessible and are protected from user access. In this …

This paper studies the synergies between memory corruption vulnerabilities and speculative
execution vulnerabilities. We leverage speculative execution attacks to bypass an important …

Meltdown and Spectre enable arbitrary data leakage from memory via various side
channels. Short-term software mitigations for Meltdown are only a temporary solution with a …

Hundreds of millions of mobile devices worldwide rely on Trusted Execution Environments
(TEEs) built with Arm TrustZone for the protection of security-critical applications (eg, DRM) …

In modern computer systems, user processes are isolated from each other by the operating
system and the hardware. Additionally, in a cloud scenario it is crucial that the hypervisor …
