Notarized Agents: Receiver-Attested Confidential Receipts for AI Agent Actions
Researchers propose Sello, a cryptographic protocol that addresses a critical vulnerability in AI agent observability by having external services sign tamper-evident receipts of agent actions rather than agents logging their own activity. The system uses receiver-side signing, encryption, and public transparency logs to create an independent audit trail that prevents compromised agents from falsifying records.
