Overview
For over 45 years, Micro Digital has been a trusted provider of firmware design services to OEMs, initially founded in 1975. We’ve evolved to focus on enhancing the security of microcontroller-based embedded systems and IoT devices, recognizing the growing threat landscape.
SecureSMX utilizes Cortex-M Memory Protection Units (MPUs) to create fully isolated partitions, limiting the impact of potential security breaches. Our approach prioritizes a layered security strategy, moving vulnerable code into umode partitions and employing runtime limiting and resource control. We offer full support for SecureSMX, including partition definition and secure framework development.
SecureSMX is now available under a dual license – GPLv2 or commercial – and can be freely downloaded from our GitHub repository: https://www.github.com/Micro-Digital/SecureSMX.
