SiFive ShieldSiFive Shield << SiFive WorldGuard is a fine-grain security model for isolated code execution and data protection. SiFive Worldguard offers SoC level information control with advanced isolation control, based on multiple levels of privilege per world, and an unlimited amount of worlds. SiFive WorldGuard offers core-driven and process-id driven modes for multi-domain security, to offer data protection for core, cache, interconnect, peripheral, and memory.>> The above sounds like multiple roots of trust to me. Here's Rambus - I do not see this done by SecureRF: <<Multiple Roots of Trust The CMRT supports multiple roots of trust, with hardware ensuring isolation of resources, keys and security assets. Each entity – such as a chip vendor, OEM or service provider – has access to its own “virtual” security core and performs secure functions without having to “trust” other entities.>> Can someone find who else provides multiple roots of trust? |
