Matter is a smart-home interoperability protocol launched by the Connectivity Standards Alliance (formerly Zigbee Alliance) in October 2022 with Apple, Google, Amazon, and Samsung as principal backers. It defines a common IP-based application layer that lets accessories from any vendor work with any compatible ecosystem (HomeKit, Google Home, Alexa, SmartThings). Matter runs over standard IP transports — Wi-Fi and the Thread mesh — with Bluetooth LE used only during commissioning. Security is a central design feature, in contrast to historically weak smart-home protocols: every Matter device has a Device Attestation Certificate signed by its vendor's PAA (Product Attestation Authority) rooted at a Matter CA, every fabric (home network) has its own root and per-device operational certificates, all device-to-device traffic is authenticated and AES-CCM encrypted, and commissioning uses SPAKE2+ with the 11-digit setup code printed on the device's QR sticker to derive a shared secret without the user typing the code into the wrong app. Matter 1.4 (2024) added home routers, energy management, solar/battery, and EV-charging device types. As an OT/IoT category, Matter is widely seen as one of the strongest commodity smart-home stacks from a security perspective.
