SYSTEMS, METHODS, AND COMPUTER PROGRAM PRODUCTS FOR BLOCKCHAIN SECURED CODE SIGNING OF AUTONOMOUS VEHICLE SOFTWARE ARTIFACTS

Provided are systems, methods, and computer program products for secure code signing of software artifacts in a permissioned blockchain for recording, distributing, and auditing of software artifacts via hash digests, artifact signatures, and worker signatures, comprising a build system worker to generate a software release blockchain, and insert software artifact blocks including a hash digest of the software artifact, a code signing worker to generate and insert a signature block of a software artifact block comprising a signature of the hash digest in the software artifact block, a check system worker to generate a check block associated with the signature block, the check block comprising an attestation verifying at least the integrity of the hash digest and the authenticity of the signature of the hash digest, and one or more processors, configured to verify the software release blockchain based at least on the check block.
