PSA-certified development kit helps meet cyber security standards

Included in the kit are the Infineon PSoC 64 Secure AWS IoT Pioneer kit, Arrow PSoC 6 IoT sensor shield, Shield2Go kits, and AWS cloud enablement with certified functional APIs and integrated dashboard for monitoring and visualisation. PSA-certified Level 2 PSoC 64 silicon offers a root-of-trust for services such as crypto and secure storage. The development kit is a pre-tested and validated reference design for end-to-end security purposes.

It is believed to be the first PSA-certified platform to use Amazon FreeRTOS, to simplify programming, deployment, and management of IoT devices, as well as delivering a secure connection to AWS Cloud services for edge computing. The PSA methodology helps to minimise development risk and time to market because the certification is designed to introduce consistent cyber-protection and cover the lifecycle of the device. Developers using the kit can be sure their devices meet the PSA Certified 10 security goals, says Arrow, including ensuring that devices are uniquely identifiable and securely attestable.

Other safeguards are that only authorised software can be executed. There is also support for isolation and secure updates while preventing unauthorised rollback. The PSA and Arm co-founded the PSA-certification which monitors a device’s security status and restricts the secure processing environment solely to trusted devices.

Arrow advises that users “can be confident they have covered all these challenges, while leveraging the PSoC 64 RoT and approved Trusted Firmware-M (TF-M) for Arm Cortex-M processors”.

The development kit is intended to help device manufacturers build security into end products and enable “security adoption at scale and reducing the barriers and costs associated with security best practice,” said “David Maidment, senior director, secure devices ecosystem at Arm.

The kit has been evaluated by SGS Brightsight, an independent security evaluation laboratory, and is PSA Certified Level 1.
