Intel's Software Guard Extensions (SGX) promises an isolated execution environment,
protected from all software running on the machine. As such, numerous works have sought …

WebAssembly is revolutionizing the approach to develo** modern applications. Although
this technology was born to create portable and performant modules in web browsers …

In the last years, there has been a rapid increase in microarchitectural attacks, exploiting
side effects of various parts of the CPU. Most of them have in common that they rely on …

There is a long history of side channels in the memory hierarchy of modern CPUs.
Especially the cache side channel is widely used in the context of transient execution attacks …

Microarchitectural attacks threaten the security of computer systems even in the absence of
software vulnerabilities. Such attacks are well explored on x86 and ARM CPUs, with a wide …

We present the design, implementation, and evaluation of SysXCHG: a system call (syscall)
filtering enforcement mechanism that enables programs to run in accordance with the …

Since the disclosure of Spectre, extensive research has been conducted on both new
attacks, attack variants, and mitigations. However, most research focuses on× 86 CPUs, with …

CPU port contention has been used in the last years as a stateless side channel to perform
side-channel attacks and transient execution attacks. One drawback of this channel is that it …

Last-level cache side-channel attacks have been mostly demonstrated in highly-controlled,
quiescent local environments. Hence, it is unclear whether such attacks are feasible in a …

Interrupts are critical hardware resources for OS kernels to schedule processes. As they are
related to system activities, interrupts can be used to mount various side-channel attacks (ie …
