Understanding Software Provenance Attestation: The Roles of SLSA and in-toto
A software provenance attestation is a signed document that associates metadata with an artifact, encompassing details like the artifact’s origin, build steps, and dependencies. This information is critical for verifying the artifact’s authenticity and integrity. Featuring a cryptographic signature, provenance attestation ensures the document remains unaltered, playing a vital role in mitigating supply chain attacks. By scrutinizing the provenance of binaries, users can thwart the execution of malicious code on their systems. Let’s delve into some concrete examples:
