SmuFuzz: Enable Deep System Management Mode Fuzzing in Fully Featured UEFI Runtime Environment

As part of the UEFI standard, System Management Mode (SMM) was introduced on x86 processors to handle critical hardware events. With strict access control to this operating mode, SMM applications run at a high privilege level (known as Ring-2), in which they have (almost) unlimited access to system resources. However, vendors commonly use memory-unsafe system programming languages to develop SMM applications, which makes them vulnerable to memory corruption and an appealing target for attackers. Fuzzing is

System Software Design for Undiluted Attestation

In trusted execution environments, the authenticity and security properties of a computer system are determined by examining its attestation. Reviewing the attestation should be sufficient to evaluate the system's correctness; however, this is not the case today. Proprietary system software cannot be audited for security, while existing isolation abstractions fail to capture important nuances, such as the existence of transient-execution attacks. In this thesis, we demonstrate that, through software-only c

Challenges of Memory Management on Modern NUMA Systems

Baptiste Joseph Eustache Lepers, Mohammad Dashti Rahmat Abadi

The latency of memory access times is hence non-uniform, because it depends on where the request originates and where it is destined to go. Such systems are referred to as nonuniform memory access (or NUMA). Current x86 NUMA systems are cache coherent (cal ...

MEX, a programming language that supports discrete event simulation

Introduces a programming language called MEX. It supports distributed programming, symmetric inter-process communication and synchronization and a virtual time mode. The virtual time mode makes the language suitable for discrete event simulation. MEX has been used to build a simulation of a Wide Area Network, which is presented
