Trusted Execution Environment (TEE) with Open Processor Cores
Download SlidesAbstract
We started a project to establish the technology of the TEE with open processor cores, and I’ll introduce the project. The Kerckhoffs's Principle is a rule read as "The design of a system should not require secrecy". This means for a crypto-system, "It should be secure even if everything about the system, except the key, is public knowledge", but actual systems use propriety processor cores such as x86 and ARM, and we cannot check such systems if they comply the principle or not. In out project, we selected RISC-V as the open processor cores, and we are constructing the TEE complying the principle with the RISC-V foundation.
