## AI overview

An overview of Matter's security model, explaining how PKI, certificates, cryptography, and session establishment support trusted devices, trusted controllers, private communication, and data integrity. It also describes Matter's Device Attestation Certificate chain and the role of the Distributed Compliance Ledger.

## Source excerpt

Matter is a protocol designed with security and privacy in mind. Cryptography is widely adopted in Matter to ensure: - Trusted devices - Trusted controllers - Private communication In this post we will go through the Matter security model and investigate how these targets are accomplished in Matter. Introduction to Public Key Infrastructure# The Matter security model is based on Public Key Infrastructure(PKI), a cryptographic mechanism widely adopted in the Internet.
