Today, the Matter PKI Compliance Customer Guide for AWS Private Certificate Authority (AWS Private CA) is avaliable on AWS Artifact. This Guide provides information about how you can use AWS Private CA to help you create and operate Matter-compliant Certificate Authorities (CAs). Matter is a new smart home connectivity standard, governed by the Connectivity Standard Alliance, that allows smart home devices from different vendors to work together. For smart home devices to be Matter-compliant, manufacturers are required to certify these devices and provision them with Device Attestation Certificates (DACs).
