STMicroelectronics has ported the CommScope’s PKIWorks IoT security platform to its STM32WB wireless microcontroller unit (MCU).
The combination of PKIWorks on the STM32WB gives IoT equipment makers a turnkey solution for developing IoT devices that meet the Connectivity Standards Alliance’s Matter standard for security.
The integration simplifies manufacturing secure Matter-device-credentials development and provisioning, in addition to reducing costs and time for IoT device manufacturers as devices can be commissioned at the MCU level without developer intervention.

“As a CSA promoter, ST is committed to making Matter development seamless for all device makers,” said Nathalie Vallespin, STM32 Connectivity product line manager, STMicroelectronics. “Our #1 ranking for general-purpose microcontrollers and expertise in secure elements positions us to combine our deep understanding of device-makers’ challenges and strong knowledge of Matter to create unique collaborations like this one with CommScope. This will accelerate the adoption of Matter development through an easy and secure process for credential provisioning.”
“By integrating the CommScope Sentry PKIWorks platform with ST’s popular MCU platform, we’re offering our customers a turnkey solution to alleviate the challenges of Matter adoption, while handling the complexity, scale, and cost,” stated Bart Giordano, president, Networking, Intelligent Cellular and Security Solutions, CommScope. “CommScope and ST have a long-standing collaborative relationship, making it easy to meet growing demand for new Matter IoT devices with the expertise of two industry leaders with decades of experience at the forefront of digital security, semiconductor solutions, and device manufacturing.”
The PKIWorks platform is a secure and flexible credential provisioning and management platform, refined over decades of experience and billions of device credentials. It is now optimized for creating and delivering Matter device credentials — providing a fast track for manufacturers of all IoT devices to provide security and interoperability with the burgeoning Matter ecosystem.
The platform uses CommScope’s expertise in provisioning clients for device credential installation, particularly on resource-constrained IoT devices. These clients enable the support of a wide range of STM32 MCUs and STSAFE-A. CommScope recently integrated this lightweight provisioning client with the STM32WB55, an MCU for IoT device development and ST’s microcontroller of choice for Matter devices.
The PKIWorks platform can generate over 30 billion device credentials annually and is designed to scale to even greater capacity, and generates Matter device credentials for a wide spectrum of IoT manufacturers and service providers using the CSA-approved Root of Trust and the CommScope Product Attestation Authority (PAA).
The Provisioning Client can install various types of device credentials to STM32 and STSAFE-A —including the STM32WB55 microcontroller designed specifically for Matter devices while the TM32WB55 Matter SDK integration enables Matter Commissioning without the need for additional integration effort from device makers. It supports both factory settings and over-the-air provisioning, providing Device Attestation Credentials (DACs) and Node Operational Credentials (NOCs) to support the security lifecycle of Matter devices.
PKIWorks services are available to device manufacturers designing with the STM32 and STSAFE-A and the STM32WB with the PKIWorks client is available now and is also offered in multiple configurations to meet the diverse manufacturing environments of IoT device providers.
