Trusted Software Development Using OP-TEE

This blog aims to introduce the concept of Trusted Execution Environment (TEE) and how end users can leverage open source software to safely deploy applications that require handling confidential information.

Trusted Execution Environment (TEE) Overview

What is a TEE? What are the benefits of having a TEE?

TEE provides an isolated environment to ensure code/data integrity and confidentiality. Typical embedded systems running Linux or Android are exposed to a large number of security vulnerabilities in both the kernel and user space packages. Vulnerabilities can allow an attacker to gain access to sensitive information and/or insert malware. TEE adds an additional layer of security where code/data running on the TEE can not be accessed/tampered from the normal world OS (eg: Linux/Android). The software running on TEE (secure world) typically involves a tiny security oriented operating system (eg: OP-TEE OS) along with trusted applications. The trusted applications are meant to handle confidential information such as credit card PINs, private keys, customer data, DRM protected media, etc. and provide services to the normal world OS to make use of the confidential information without compromising it.

Webinar: Developing for Industrial IoT with Linux OS on DragonBoard™ 410c

The ever-increasing demand for connected embedded systems is driving innovation in Industrial IoT (IIoT), including designs with connected sensors, robust CPU processing, low power, and security designed and built into products from the earliest stages.

Join us for a Timesys University 4-part webinar series — Developing for Industrial IoT with Linux OS on DragonBoard™ 410c — to explore the process of building an embedded Linux based device using the Qualcomm® Snapdragon™ 410E powered DragonBoard 410c development board from Arrow Electronics. With topics that cover build systems, deployment strategy, designing-in and managing security, device appearance and ease of user interaction, you’ll gain insight into various aspects of technology and design decisions developers face when choosing to build embedded Linux based products for this increasingly demanding and expanding connected world. All sessions in this Qualcomm Developer Network sponsored series are designed to provide hands-on experience throughout the entire development process, including assembly of the development environment and its use to develop a security-rich Linux based platform and Qt based UI application for an IIoT device.
