Shifting Security's Perimeter: Why Cryptographic Model Provenance Is Now Essential

As AI agents become operationalized across enterprises, traditional supply chain security—focused on CVE scanning and code verification—proves inadequate. AI models are probabilistic black boxes vulnerable to poisoning and data manipulation, requiring cryptographic proof of origin and training provenance. The EU's Cyber Resilience Act (effective September 2026) is making this shift mandatory, forcing organizations to implement AI Bills of Materials (aiBOM) and fundamentally transforming security from code-level verification to model-level provenance validation.
