Bridge: A Leak-Free Hardware-Software Architecture for Parallel Embedded Systems
Year: 2024
Type: conference-paper
Abstract: Embedded and Internet of Things (IoT) devices are increasingly ubiquitous and process increasingly sensitive data. As a result, such devices must uphold security in addition to functional safety to avoid unintended information leaks. To react this change of environment, developers deploy conventional mechanisms such as memory isolation and priority scheduling to achieve aforementioned goals. While such techniques are resilient against attacks that endanger a device's functional safety, they are less effective in maintaining security as they ignore information leaks through timing channels, such as through scheduling policy and implicit microarchitectural state. Recent advances in timing-safe systems, in turn, limit themselves to time-shared systems without parallelism. This is problematic in the face of responsiveness and real-time constraints which are often found in embedded devices.
