  • Secure OTA Updates for Cortex-M Devices with FreeRTOS
    IoT devices are getting rapid adoption in every market segment and becoming a major target for cyberattacks. A significant proportion of attacks on IoT devices happens due to a lack of software updates once commissioned in the field or updates done insecurely. Cyber attackers often target vulnerabilities in outdated software components to take control of […]

  • Why Write Another MQTT Library?
    Libraries capture a set of decisions about how the world should work. If you're lucky, the model in the library is a suitable match for your needs and constraints. If you're not lucky, you either end up with something that's wasteful, or requires changes, or you must search for a different library that's a better […]

  • Benefits of Using the Memory Protection Unit
    The device you are reading this on relies on your processor’s Memory Management Unit (MMU) to sandbox each running application. Without its ability to prevent erroneous or even malicious accesses to the wrong memory – be it the operating system’s data or another task’s – consumer devices would be a minefield of bugs and security […]
