Trusted Execution Environment Provisioning (TEEP) Architecture
draft-ietf-teep-architecture-02
Abstract
A Trusted Execution Environment (TEE) is designed to provide a
hardware-isolation mechanism to separate a regular operating system
from security-sensitive application components.
This architecture document motivates the design and standardization
of a protocol for managing the lifecycle of trusted applications
running inside a TEE.
