Secure and Isolated Execution

his open source trusted execution environment implementation is originally based on Arm TrustZone* and maintained by Linaro. OP-TEE* for Intel® Architecture is the hardware virtualization-based OP-TEE solution for x86 systems from Intel. It has a fully compatible design and maximum reuse of OP-TEE. It's a full environment including an operating system, services, and APIs that consist of the following:

• Operating system and kernel that:
  • Supports virtual address space isolation and privilege isolation
  • Works in event-driven model by request from the Rich Execution Environment (REE)
• Drivers for a Linux* kernel
• Libraries for client and trusted applications
• Hypervisor that uses Intel® Kernel Guard Technology (Intel® KGT), which Intel open sourced in 2015.

Features

• Secure Execution: Run trusted applications in isolated environments to protect against unauthorized access.
• Hardware Virtualization: Utilize Intel's hardware virtualization technology for enhanced security.
• Comprehensive Environment: Includes a full operating system, services, and APIs for trusted applications.
• Flexible Integration: Easily integrate with existing systems and workflows.
• Detailed Documentation: Access extensive resources for implementation and troubleshooting.
