Micro Digital announces MCU Security Solution

We are pleased to announce the release of SecureSMX, a high-security RTOS for MCU-based products, such as IoT devices. It uses the hardware security features of Cortex-M-based processors to create hacker-proof, isolated partitions and to prevent nefarious hacker activities from within partitions.

SecureSMX allows vulnerable code in existing devices to be partitioned off from mission-critical code with little or no modification to the latter. Security improvement can be accomplished iteratively over time.

It also provides secure frameworks for building new systems featuring baked-in security and strong enforcement of good programming practices, which result in reduced system integration time and higher-quality code. Agile and CI/CD practices can be employed for developing code within partitions.

Other features of SecureSMX are:

  • Full support for hmode/pmode/umode operation of Cortex-M processors to achieve full partition isolation.
  • SVC exception implementation provideslimited system services from umode.
  • Advanced MPU control with many innovative features, such as dynamic regions and auxiliary region swapping, to achieve high security and to reduce memory waste and overcome MPU limitations.
  • Debugger plugin shows task Memory Protection Arrays per task, MPU regions, selected events, and timelines to greatly aid debugging.
  • eheap for embedded systems permits multiple heaps, each configured for its partition and offers self-healing, block merge control, and other advanced features.
  • Partition portals for communications and message-based API implementation between partitions that preserve strong isolation.
  • Runtime limiting to control processor use by untrusted tasks while allowing trusted tasks to run freely.
  • Tokens to limit access to RTOS objects and the operations upon them.
  • Moving most ISR code from hmode to umode for improved security.
  • Partition stop, reboot, and update to allow a device to continue doing its primary function while the security team develops patches.
  • Zero-day protection.
  • Insider attack protection by enabling siloing of development and support teams.

For more information, ebook, and modifiable demos please visit www.smxrtos.com/securesmx. Now is the time to build security into your device.

Availability and Licensing

SecureSMX is available now for Arm Cortex-M v7 and v8 processors. Training, consulting, and porting services are available.
