NXP integrates NFC in lock for Matter devices

The EdgeLock SE051H is a secure element designed for the Matter protocol by NXP Semiconductor. It integrates NFC (near field communication) functionality to simplify secure onboarding of Matter devices in the smart home, said the company.

The latest addition to NXP’s portfolio of Matter devices, the EdgeLock SE051H is a single chip with integrated NFC, designed to simplify the secure and seamless onboarding of Matter devices. It can also enable new smart home user experiences, such as suggested automations, installation videos and other content with just the tap of an NFC-enabled phone. 

The Matter standard, designed by the Connectivity Standards Alliance (CSA), is designed to ease device interoperability challenges within the smart home network. It raises smart home security with features such as cryptographic keypairs, digital certificates, and other security-related hardware and firmware requirements to protect smart home devices. The EdgeLock SE051H is optimised to support these requirements.

“The single-chip EdgeLock SE051H makes it easy for developers to secure their Matter-certified smart home devices, while integrated NFC improves the end user Matter experience and allows device makers to differentiate based on that user experience,” observed Philippe Dubois, senior vice president and general manager, secure transactions & identification, NXP.

The EdgeLock SE051H is Common Criteria EAL 6+ certified and supports the cryptographic operations needed for a Matter-certified smart device. This includes Matter device attestation and certificate-based authentication with ECC cryptography and NIST P-256 curve, as well as the SPAKE2+ algorithm for password authenticated key exchange. It also includes key security functions such as ECDSA, ECDH, and True Random Number Generator to protect the Matter protocol. In addition, the EdgeLock SE051H has an integrated NFC interface and Type-4 Tag capability.

Matter’s security requirements include a device attestation certificate, which confirms device authenticity, demonstrates trustworthiness and establishes an authenticated connection with the larger Matter network. NXP is one of the first semiconductor manufacturers to have been granted trusted Product Attestation Authority status by the CSA, with its EdgeLock 2GO service for securely provisioning IoT devices. EdgeLock 2GO, combined with EdgeLock SE051H, can pre-inject credentials directly into silicon at silicon manufacturing or can deliver the credentials securely over-the-air (OTA) with end-to-end security to simplify supply chain management and in compliance with the Matter standard.
