IoT ecosystem has strengthened security

21-02-2020 | U-Blox | New Technologies

U-blox is strengthening the security of IoT ecosystems created upon its dedicated LTE-M and NB-IoT chipset by implementing a key set of security features endorsed by the GSMA. Support for the IoT SAFE (IoT SIM applet for secure end-to-end communication) implementation guide is to be incorporated in a software maintenance release for the company's devices based on the UBX-R5 chipset, such as the new SARA-R5 series in 2020.


The series is a 5G-ready, software-configurable family of IoT devices that support LTE-M and NB-IoT communications over multiple radio bands. It comprises a secure element, certified to the Common Criteria EAL5+ High-security assurance standard, which also serves as a hardware root of trust for processes including authentication and encryption.


The GSMA started the IoT SAFE recommendation in December 2019. It allows IoT device manufacturers and service providers to utilise a SIM as a robust and scalable hardware RoT to protect IoT data communications. This will make it simpler to securely establish a (D)TLS session with an application cloud/server, easing the process of provisioning and managing millions of IoT devices.
