Hi Michael,

I have not heard about Matter specifically, but there has been some discussion in the TCG and the Global Semiconductor Alliance of using a DLT to help validate endorsements from the manufacturers.

In context of RATS WG and Endorsements, the challenge is not just about validating signatures over SBOM files and firmware/software files,  but also ensuring that "integrity measurements" for specific hardwares (e.g. TPM PCRs) are correct.


BTW. Here is a link to a presentation from Intel about using DLTs for Endorsements (I think there is also al older RSA and NIST presentations):

Have you seen, btw, that MATTER is using a ledger for distribution of
Endorsements for their remote attestation system?
