STMicroelectronics has introduced ST MatterConnect, a service that preloads the certification information required for Matter-capable smart home devices into secure semiconductors. The company announced the service on October 26, positioning it as a way for device manufacturers to avoid building separate secure injection systems to manage device attestation data.
What ST MatterConnect supplies
ST MatterConnect stores the Matter device attestation certificate (DAC), encryption keys, and product and version metadata directly on ST security components at the company’s in-house facilities. According to ST, the company’s production environment is approved in the Matter certificate issuance framework as a Product Attestation Authority (PAA) and a Product Attestation Intermediate (PAI), which it uses to generate and load the certification information onto chips.
- Preloaded credentials: DAC, encryption keys, product and version information
- Device on-boarding support: facilitates Matter device registration and attestation during network join
- Security infrastructure: production facilities and workflows aligned with Matter’s PAA/PAI model
Products covered and technical elements
ST told integrators and manufacturers that the service will be available on specific ST components used in Matter device designs. The two products named are the ST25DA-C near-field communication (NFC) tag and the STSAFE-A120 secure element. ST said the ST25DA-C supports the device-registration flow for Matter network onboarding, while the STSAFE-A120 securely stores the device’s certification information and performs secure connection setup and data integrity verification.
| manufacturer | component | role |
|---|---|---|
| STMicroelectronics | ST25DA-C | near-field tag for Matter registration |
| STMicroelectronics | STSAFE-A120 | secure element for storing DAC and keys, secure setup |
Implications for manufacturers and integrators
By generating certification information and loading it in its own security-certified facilities, ST said manufacturers can reduce the need to build separate secure information-injection systems. That can remove a logistical and capital hurdle for companies launching Matter devices, particularly smaller vendors that lack dedicated secure programming infrastructure.
ST’s announcement frames the service as an end-to-end option that combines chip supply with attestation provisioning. The company’s role as a PAA and PAI in the Matter certificate issuance framework provides the chain of trust for device attestation that Matter requires when a product joins a network.
The move also underscores the continued maturation of Matter-related supply-chain services: as the standard gains adoption across lights, plugs, locks and cameras, manufacturers and integrators will look for ways to streamline secure onboarding and certification without adding complex factory processes.
ST’s release describes the capability as available now in conjunction with the named ST components; the company did not, in the material provided, list additional product families, pricing or program enrollment details.
