**Case Study: Securing MMU-less Linux Using CHERI** MMU-less Linux variant lacks security because it does not have protection or isolation mechanisms. It also does not use MPUs as they do not fit with its software model because of the design drawbacks of MPUs (\\ie coarse-grained protection with fixed number of protected regions). We secure the existing MMU-less Linux version of the RISC-V port using CHERI. CHERI is a hardware-software capability-based system that extends the ISA, toolchain, programming languages, operating systems, and a ... ⌘ Read more
