MultiZone™ Security is the first Linux enclave for RISC-V. The MultiZone™ demo shows how to secure the deterministic behavior of mixed-criticality systems where Linux and Real-Time come together in a single PolarFire SoC device. For safety-critical applications that require trusted workloads on untrusted platforms, MultiZone™ Security provides software-defined hardware-enforced separation for multiple enclaves, with full isolation of data, programs and peripherals. Contrarily to legacy thick hypervisor solutions: MultiZone™ is completely self-contained, it presents an extremely limited attack surface, it's formally verifiable, and doesn't require changes to existing software. With MultiZone PolarFire Edition, open source software, third party binaries and legacy code can be configured in minutes to achieve unprecedented levels of safety and security.
