Tech: AP-TEE Task Group

The RISC-V Application Platform - Trusted Execution Environment Task Group (AP-TEE TG) will collaborate to define the reference architecture for confidential computing on RISC-V platforms - including the ABI required to enable systems software to manage confidential workloads on a multi-tenant platform, while keeping the OS/hypervisor and entities that develop the OS/VMM and/or operate/manage the platform outside the TCB. The TG will design the interfaces to comprehend existing (ratified) ISA and ensure extensibility of the interfaces to new Architectural ISA extensions as required for security or performance of confidential workloads. In addition to the normative specifications mentioned, the TG will produce a security architecture analysis per the threat model agreed upon as a living (non-normative) document supporting security recommendations, implementation-specific guidelines and relevant standard protocols for attestation for implementers of the AP-TEE capability on their RISC-V platforms.
