AWS Private Certificate Authority (AWS Private CA) now supports revocation for Matter certificates. Matter is an industry standard for smart home devices that provides seamless and secure cross-vendor connectivity for devices like light bulbs, door locks, and media devices. You can use AWS Private CA to issue digital certificates for identifying Matter devices. Matter 1.2 introduced revocation support for device attestation certificates (DACs) to improve the security of the smart home standard. With this new support for revocation from AWS Private CA, you can maintain Matter standard compliance without any disruption to your existing Matter certificate authorities (CAs).
