About Matter
A Unified Approach to IoT Device Development
Matter drives the convergence between the major Smart Home IoT ecosystems to create one easy, reliable, and secure wireless protocol to connect all IoT devices and networks in homes.
Matter Benefits Developers and Consumers
Matter leverages existing IP technologies including Wi-Fi and Thread to build a unified wireless connectivity ecosystem and IP-based networking provides manufacturers with simplified development while improving device compatibility for consumers. Motivated by the belief that connected experiences should become more reliable, secure, and work effectively together, the Connectivity Standards Alliance (CSA) launched Matter (formerly known as Connected Home over IP project) to make it easier for device manufacturers to build devices that are compatible with smart home and voice services such as Amazon’s Alexa, Apple® Siri®, Google Assistant™, and others.
Matter also builds in defenses against a wide variety of threats with a security architecture based on “security by design” and “zero trust”. As part of this, Matter builds in security measures so that every message is protected.
Developer Benefits:
-
Simplifies development, lowers development & operational costs
-
Community collaboration improved quality, expedites process and captures broader use-cases
-
Faster time to market, as developers can leverage existing implementations
-
Opensource and trusted standard cryptographic algorithms with well protected keys
Consumer Benefits:
-
Matter products should be easy to purchase, set up and use
-
Devices from multiple brands work natively together
-
Consumers are in control of the privacy and authorization for interaction with the devices
