May as well throw out a plug for https://openssf.org/, and for https://www.sigstore.dev/ in particular, here.

A recent* Open Source Summit session gave an example of signing SBOMs using sigstore, if I recall correctly, though I don’t recall the details.

* I say “recent” – could have been SupplyChainSecurityCon back in October. My sense of Time is out of whack since the pandemic.

Sandeep,

I’m not aware of any specific guidelines for signing SBOM’s (SPDX and CycloneDX).

REA’s signs SBOM’s using PGP as this seems to be the easiest method to sign stand-alone text files, including SBOM’s.

We simply have to make our public key available for verification of signed SBOM’s.

The IETF is working on a new supply chain integrity, transparency and trust initiative (SCITT) that aims to produce a method for signing and verifying attestations, including SBOM’s.
