Securing Device Credential Provisioning: Matter and the Wider IoT Ecosystem

The rise of Matter as a unifying IoT standard brings new security challenges to device manufacturers, especially in credential provisioning during production. Each device must be provisioned with a unique Device Attestation Certificate (DAC) to ensure trust and interoperability.

Adding credential provisioning to manufacturing introduces two key challenges: security risk and production complexity. If cryptographic key pairs are generated outside the device—at programming stations or in central systems—they become attractive targets for cyberattacks. A single breach could compromise a large volume of devices at once. At the same time, fast-paced production raises the risk of operational errors, such as assigning the same credential to multiple devices, leading to duplication and trust issues in the field.

This session explores a secure and efficient approach for generating key pairs inside devices, reducing attack surfaces and making large-scale compromise far more difficult. We will also discuss methods to simplify certificate workflows to avoid production delays and errors.

The solution ensures DAC private keys never leave the device and supports efficient, error-resistant factory deployment. While the discussion is framed around Matter, the concepts are broadly applicable across IoT ecosystems and hardware platforms, providing vendors with a scalable path and proven best practices to secure device manufacturing across diverse applications.
