SOFTWARE RUN-TIME PROVENANCE

摘要

An executing first computing module verifies the run-time provenance of an unverified second computing module. A signed certificate identifying an author of the second computing module is received at the first computing module. An association between the signed certificate and the second computing module is verified. A first provenance certificate and associated private key signed by the first computing module and identifying a runtime provenance of the second computing module is then generated, and the first provenance certificate is published to the second computing module. A chain of signed certificates, including provenance certificates and a static identification certificates, can be published. Each provenance certificate in the chain verifies the integrity of a layer of execution, and the plurality of static identification certificates identifies a respective author of the computing module associated with each layer of software. The provenance of the second computing module can be recursively traced through the published chain of certificates.
