Secure Elements for IoT


some connected and unattended devices (like IoT nodes) require reliable protection against misuse. A secure element works as a “root-of-trust” for IoT devices ensuring tamper-proof authenticity and secure data transfer. For a small-/medium size project a distributor like Digi-Key will supply parts, they offer a good variety of secure elements from different manufacturers like NXP, Infineon, Microchip or STMicroelectronics. I reviewed major candidates, see attached file.

Some manufacturers offer in-house chip provisioning (i.e. for loading of customer-specific credentials), others ask for a signed NDA before comprehensive documentation is being provided. Online support might be poor, so be careful to short-list suitable candidates, which are offered as ready-to-use pre-provisioned versions and available from distributors off the shelf.

Take care,
