Sequitur Labs Collaborates with Linaro to Lower Barriers to IoT Security Education for Raspberry Pi Maker Community

Pi 3 becomes the lowest cost platform to enable bare metal debugging for the ARM®v8 architecture and access to ARM® TrustZone® technology

SEATTLE, June 8, 2016 /PRNewswire/ - Sequitur Labs Inc. today announced a port of Linaro OP-TEE to the popularly used Raspberry Pi 3 platform. With this port, many more developers can begin learning about and using technologies like ARM® TrustZone®, ARM Trusted Firmware and Linaro OP-TEE while lowering the cost to learn these technologies.

Better Security Begins with Developer Education, Easy Access

TrustZone is an on-chip security enclave that provides hardware isolation and protection for sensitive material such as cryptographic keys, algorithms and data. TrustZone has been widely adopted on mobile phones, set-top boxes and billions of devices in the last decade. It is rapidly becoming the security technology of choice for connected embedded device makers looking to provide critical trusted functions to secure Internet of Things (IoT) products. Therefore, it is important that IoT developers understand this foundational security technology and its applications.

OP-TEE, an open source project managed by Linaro, is a trusted execution environment (TEE) project that makes use of ARM TrustZone technology. The availability of OP-TEE on the Raspberry Pi 3, which is based on Broadcom’s BCM2837 SoC, puts this technology in the hands of developers at the lowest possible cost.

“This work is about giving back to the community. It is critical for IoT devices that security be built-in, not bolted on. This begins with educating developers and makers and enabling them with the right tools. A practical bonus is that trusted applications they build for OP-TEE on the Raspberry Pi could be deployed on other TrustZone enabled chips,” said Philip Attfield, CEO of Sequitur Labs.

Developers seeking to learn more about embedded systems security and experiment with building trusted applications will have access to educational material and the necessary software and hardware components from the Linaro website https://github.com/OP-TEE/optee_os/tree/master/documentation from Tuesday, July 11. Source code will be available at https://github.com/OP-TEE and https://github.com/linaro-swg. The required hardware-software package includes:

  • Raspberry Pi 3
  • MicroSD card
  • Bus blaster
  • Custom Cable to enable bare metal debugging
  • Single system Image: 64-bit Linux, ARM Trusted Firmware, OP-TEE
  • OpenOCD and configuration file for the Pi 3
  • Documentation including code samples and a quick start guide

“It is fantastic to see Linaro’s OP-TEE being made available to a broader audience. The Linaro Security Working Group (SWG) was created to help accelerate the delivery of high quality secure products across the ARM ecosystem and this effort by Sequitur Labs is a step in that direction,” said Joakim Bech, director of the Linaro Security Working Group. “The OP-TEE software package is now available for all new and previously shipped Raspberry Pi 3s. Developers only need to download the software components from the Linaro website. Support will be provided through forums on Linaro.”

Extending Raspberry Pi’s Appeal via Bare Metal Debugging

The additions made by Sequitur Labs also include a modified uBoot process making bare-metal debugging easy for developers via JTAG. This level of access makes it possible to investigate the Pi 3 in a very controlled state while having access to all the various parameters.

“Enabling the open source Trusted Execution Environment, OP-TEE, on the new Raspberry Pi 3 will allow IoT developers and students to learn the concepts of a GlobalPlatform TEE and how to develop trusted code on ARM Cortex®-A processors," said Rob Coombs, director of security marketing, ARM. “Billions of devices already use ARM TrustZone as a foundation for security and this project will broaden developer access to the Trusted Execution Environment that sits on top of it. It will enable the development of IoT devices with a deeper level of protection.”

The release of OP-TEE on the Raspberry Pi 3 and the Pi 3 hardware enables hardware-based security for product trial development and educational purposes. It provides a foundation on which to create commercial grade devices.
