Multi-Zone Security for RISC-V Simplifies the Terrible TEEs
Oct 22, 2018

Trusted Execution Environments (TEEs) such as Arm TrustZone, while well-intentioned, present challenges for engineers. First, they doesn’t allow for partitioning between many sensitive functions within a secure domain, and, perhaps more importantly, they can be very difficult to use. Don Barnetson of Hex-Five discusses TEEs and multi-zone security, a new technology for the RISC-V ISA that enables limitless partitions, each with its own set of resources. And, it has minimal impact on existing development processes and tools.
