Explore Matter Security through continuous verification, re-attestation, firmware integrity checks, and Zero Trust principles for secure smart homes. Matter basically onboard devices through a pre-defined set of security rules. These rules are applied when users want to onboard the devices. Through device attestation and certificate-based authentication, Matter verifies that a device is genuine before allowing it to join the network and establishes an initial level of trust. This approach works well for device commissioning, but it is fundamentally a one-time verification process.
