\u2014Embedded systems are deployed ubiquitously among various sectors including automotive, medical, robotics and avionics.

\nCheriRTOS on CHERI-64, a hardware-software platform atop Capability Hardware Enhanced RISC Instructions (CHERI) for embedded systems.<\/p>\n
Our system provides efficient and scalable task isolation, fast and secure inter-task communication, fine-grained memory safety, and real-time guarantees, using hardware capabilities as the sole protection mechanism. We summarize state-of-the-art security and memory safety for embedded systems for comparison with our platform, illustrating the superior substrate provided by CHERI\u2019s capabilities. Finally, our evaluations show that a capability system can be implemented within the constraints of embedded systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
