STMicroelectronics STM32Trust cybersecurity program

Click2Contact

STMicroelectronics has launched STM32Trust to guide designers’ efforts to build strong cyber protection into IoT devices leveraging industry best practices.

STM32Trust combines knowledge, design tools and ready-to-use original ST software. These help designers take advantage of features built into STM32 microcontrollers to ensure trust among devices, prevent unauthorised access and resist side-channel attacks. All this averts data theft and code modification. Integrating all available cyber-protection resources for the STM32 family, STM32Trust helps designers implement a robust multilevel strategy leveraging security-focused chip features and software packages.

The STM32 family is based on the Arm Cortex CPU architecture and contains almost 1000 variants used in smart appliances, remote sensors, wearables, e-health devices, IoT gateways, access-controlled storage, payments and many other connected devices. Depending on the model, hardware cyber protection can include features such as customised secure boot, a random-number generator to prevent hackers observing patterns in signals, dedicated encryption co-processors and secure storage for encryption keys. ST also builds in tamper detection and firewall code-isolation mechanisms, and implements Arm TrustZone technologies for extra protection of the most sensitive code. STM32Trust is said to provide product developers with all they need to protect connected objects effectively using these features, including reference material and free software.

The STM32Trust resources including tools, evaluated reference material and source code can be downloaded free of charge from www.st.com/stm32trust.
