# Machine-Readable Assurance **Entity class:** Security and interoperability architecture ## Definition **Machine-readable assurance** is the expression of identity, authorization, provenance, sensitivity, purpose, control status, approval, and audit evidence in forms that software can evaluate and enforce. It turns compliance from a paper description into an executable trust layer. It allows a receiving system to ask: who or what is acting; which credential and authority support the action; what data may be accessed or combined; which model or service touched it; which handling rules follow the object; and whether the transaction can be reconstructed. ## Boundary Common representations permit interoperability. They do not merge institutions or transfer legal powers. Policy gates remain specific to mission, data, jurisdiction, classification, and purpose. ## Relationships - **institutional foundation:** [[wiki/Unified Federal Information Security Framework|Unified Federal Information Security Framework]]. - **control foundation:** [[wiki/NIST SP 800-53|NIST SP 800-53]], [[wiki/CNSSI 1253|CNSSI 1253]], and [[wiki/ICD 503|ICD 503]]. - **identity and signatures:** [[wiki/Federal Public Key Infrastructure|Federal PKI]], [[wiki/PIV and CAC|PIV/CAC]], and [[wiki/Digital Signature Chain|digital-signature chains]]. - **operational result:** [[wiki/Federated Trust Fabric|Federated Trust Fabric]], [[wiki/Operational Onboarding|Operational Onboarding]], and [[wiki/AI Fusion|AI Fusion]]. - **source:** [[research/Machine-Readable Assurance and the Convergence of Intelligence|Machine-Readable Assurance and the Convergence of Intelligence]]. ## Sources / Provenance - [NIST — Unified framework announcement, June 16, 2009](https://www.nist.gov/news-events/news/2009/06/nist-dod-intelligence-agencies-join-forces-secure-us-cyber-infrastructure) - [ODNI — ICD 503](https://www.dni.gov/files/documents/ICD/ICD-503.pdf)
