     Trusted Execution Environment Provisioning (TEEP) Architecture
                    draft-ietf-teep-architecture-01

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.
