Matter compliance rapidly and at scale

(LEHI, Utah) – (October 11, 2022) – DigiCert, Inc., the world’s leading provider of digital trust, announced today that its Root Certificate Authority (CA) is approved by the Connectivity Standards Alliance (Alliance) for Matter device attestation. As the first Matter-approved root CA, also known as a Product Attestation Authority (PAA), DigiCert can now provide rapid time to market for smart home manufacturers looking to earn the Matter seal on their products.

A multi-year participant in Matter, DigiCert contributed its expertise to the security and attestation components of the standard and has the scalable technology to enable an efficient path to compliance.

“The introduction of Matter to the smart home industry is an exciting move that improves interoperability between devices and raises the bar for security, creating a more efficient and secure experience for consumers,” said DigiCert VP of IoT Security Mike Nelson. “DigiCert has been involved in building the Matter standard for several years, and we’ve already helped many leading companies evaluate their device attestation procedures using our test Certificate Authority. Now, with our PAA approved for production, we are ready to help customers save time in achieving Matter security compliance.”

Matter participants may gain the following benefits by partnering with DigiCert:

Matter is an industry-led effort of the Alliance bringing together the world’s leading manufacturers to achieve secure, reliable and seamless use of smart home devices. Matter enables IP-based networking and communication across smart home devices, mobile applications and smart home ecosystems. Matter devices offer consumers assurances of secure use through a consortium-led standard for authenticating device identity that only allows Matter-certified devices to connect to the network.

“DigiCert has been an integral part of the development of the attestation policy for the Matter release and its inherent improvements in the security of the IoT space,” said Chris LaPre, Director of Technology at the Connectivity Standards Alliance. “Device attestation allows existing Matter devices to locally confirm new ones when they have been recognized by the local network, and quickly remove non-compliant devices when needed. Consumers are no longer under the burden of ensuring new devices are secure; it happens automatically.”
