Setting the New Standard for Trust in Smart Home with Matter Protocol

Mike Nelson

For the first time, the biggest names in smart home (Apple, Amazon, Google, Samsung and more) have come together to agree on a common set of standards, which will allow for secure, reliable device interoperability. Smart home device manufacturers that do not act now to get involved could get left behind. At DigiCert, we’ve supported the Matter standard throughout the process and believe it will promote greater interoperability, security and digital trust for consumers.

The Matter specification is nearly finalized and it’s time for all players in the industry to start working together to produce Matter-compliant devices.

What is the Matter protocol?

The Matter protocol is the first effort to provide a standard for secure, reliable interoperability for smart home devices, mobile apps and cloud services. It’s not a replacement for existing platforms, but a common way for devices and platform providers to communicate securely and reliably.

Originally known as CHIP (Connected Home Over IP), members of Matter include Amazon, Apple, DigiCert, Google, Samsung and other major players in the smart home space. There are over 250 companies involved in Matter, and DigiCert has played a key role in developing the security related aspects of the standard. This broad support will ensure that all devices, apps and platforms can work seamlessly together. Additionally, Matter is available globally and is an open-source standard.

Matter has made it clear that the goal is to have compliant devices on the shelf for the 2022 holiday season. Manufacturers should prepare now to put the right pieces in place to ensure compliance with the specification. Products that meet the specification will be able to place the Matter logo on their products, which will assure customers that the device will be secure and will work seamlessly with any other Matter-compliant device. The Matter seal will become a recognized and sought after branding for consumers across the globe. When your customers see the Matter logo on your device, they will know they can trust it to connect seamlessly and securely.

PKI & the road to compliance with Matter

Public key infrastructure (PKI) is a tried and true standard for achieving digital trust. For years, critical industries have used PKI when devices from multiple manufacturers need to seamlessly exchange information and work together in a secure way. So, while the smart home industry is just beginning down the path to create interoperability and security, they are learning from best practices done in other industries.

As the global leader in digital trust, DigiCert was invited to help develop the PKI specification for the Matter protocol. To achieve this multi-manufacturer interoperability, the first step is creating shared roots of trust that are securely created and managed by appropriate parties like DigiCert. Once the trusted roots are created, issuing CAs that have been signed by these trusted roots are created and used to issue the trusted end entity, or device attestation, certificates. However, managing your certificate infrastructure will require robust capabilities for traceability, revocation and reporting. This is where we recommend a certificate management platform like DigiCert® IoT Trust Manager.
