Micro Digital Announces MCU Security Solution
29 March 2024 - 2:00AM
Business Wire
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 provides limited 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.
