Trusted execution environments (TEEs) see rising use in devices from embedded sensors to
cloud servers and encompass a range of cost, power constraints, and security threat model …

Recent attacks have broken process isolation by exploiting microarchitectural side channels
that allow indirect access to shared microarchitectural state. Enclaves strengthen the …

With its huge real-world demands, large-scale confidential computing still cannot be
supported by today's Trusted Execution Environment (TEE), due to the lack of scalable and …

Trusted execution environments (TEEs) are becoming a requirement across a wide range of
platforms, from embedded sensors to cloud servers, which encompass a wide range of cost …

Side-channel attacks on microprocessors, like the RISC-V, exhibit security vulnerabilities
that lead to several design challenges. Hence, it is imperative to study and analyze these …

Hardware enclaves rely on a disjoint memory model, which maps each physical address to
an enclave to achieve strong memory isolation. However, this severely limits the …

We present Citadel, to our knowledge, the first side-channel-resistant enclave platform to run
realistic secure programs on a speculative out-of-order multicore processor. First, we …

The rising tide of attacks, in the recent years, against microprocessors and the system-on-
chip (SoC) space as a whole, has led to a growing number of studies into security of SoCs …

In recent years, an increasing number of hardware devices started providing programming
interfaces to developers such as smart NICs. Processor vendors use microcode to extend …

Computing architectures come in all forms and shapes, and they impact our daily lives
significantly. Smartphones are omnipresent, most jobs require daily interactions with …
