AN5156. Application note Introduction to STM32 microcontrollers security Introduction This application note presents the basics of security in STM32 microcontrollers. Security in microcontrollers encompasses several aspects including protection of firmware intellectual property, protection of private data in the device, and guarantee of a service execution. The context of IoT has made security even more important. The huge number of connected devices makes them an attractive target for attackers and several remote attacks have shown the vulnerabilities of device communication channels. With IoT, the security extends the requirements for confidentiality and authentication to communication channels, which often require encryption. This document is intended to help the building of a secure system by applying countermeasures to different types of attack.
protect a system, it is possible that a security breach is found and exploited during the device lifetime. This last point makes necessary to consider how the device firmware is updated to increase its security (see Section 5.2.2 Secure firmware update (SFU)).
