SiFive Shield: An Open, Scalable Platform Architecture for Security | James Prior, SiFive

SiFive Shield is an open, scalable platform architecture designed to enable whole SoC security for RISC-V designs. The needs of modern SoC design dictate the need for a scalable solution for security, offering a low trusted computing base with clear root-of-trust and crucially, is auditable. Customization is also key, as a single offering fits all approach does not align to the needs of the next generation of domain specific processors now being designed.

Securing the RISC-V revolution requires a scalable architecture that offers per-memory protected memory regions and multi-core privilege modes. SiFive Shield and SiFive WorldGuard enable a scalable architecture with the ability to offer greater isolation.
