IoT Platform Enhances Security For Connected Devices


Security has now become an issue of high concern in the Internet of things (IoT). In pursuit of this, Express Logic announced that it has integrated the new Secure Boot and Secure Firmware Update v.2.0 software solution from STMicroelectronics with its X-Ware IoT Platform for developers using the STM32-family of ARM Cortex-M microcontrollers.

According to the company, this integration will enhance the IoT platform to fully utilize the range of security features of STM32 microcontrollers to protect connected devices like IoT endpoints. It will also help X-Ware IoT Platform developers to concentrate on their application development rather than having to devise and implement secure boot and secure firmware update schemes, making their job significantly easier.

New Secure Boot and Secure Firmware Update solution

The X-CUBE-SBSFU Secure Boot and Secure Firmware Update solution enables the update of the STM32 microcontroller built-in program with new firmware versions based on the X-Ware IoT Platform. The update process is performed in a secure way to prevent unauthorized updates and access to confidential on-device data, the company said. In addition, Secure Boot (Root of Trust services) checks and activates STM32 mechanisms, and checks the authenticity and integrity of X-Ware IoT Platform before every execution to ensure that invalid or malicious code cannot be run.


Because X-CUBE-SBSFU is built on top of STM32Cube software technology, the X-Ware IoT Platform integration will be portable across the entire range of STM32 microcontrollers, beginning with the STM32L4 and STM32L4+ series devices, the company further said.

In the announcement, the company noted: “Express Logic has already established itself as the safety leader in the embedded IoT space with its Industrial Grade approach, including pre-certification to SIL 4 and ASIL D safety standards. This new secure boot and secure firmware update services from STMicroelectronics secure boot and secure firmware update enhances security for Express Logic’s X-Ware IoT Platform for the STM32 microcontroller.”
