RFC-0002 · Standards Track · Version 1.0

Identity & Trust Framework

A universal trust layer through which humans, institutions, and artificial intelligence systems may establish verifiable relationships.

§ 00Abstract

This document defines the identity, trust, authentication, attestation, and certification framework for Svea Ark MCP.

The framework establishes how humans, organizations, governments, artificial intelligence agents, and autonomous systems can securely identify themselves and establish trust across institutional networks.

§ 01Problem Statement

Current identity systems were designed for websites. Future systems must support:

Autonomous agents
Institutional AI
Machine-to-machine agreements
Cross-border organizations
Foundation structures
Digital governance

Existing standards solve authentication. They do not solve trust. Svea Ark MCP solves both.

§ 02Core Principles

Identity is Verifiable
Identity is Portable
Identity is Auditable
Identity is Revocable
Identity is Jurisdiction Aware
Identity is Cryptographically Proven

§ 03Trust Hierarchy

Level 0

Unknown

No verification.

Level 1

Verified Human

Identity confirmed via passport or national eID.

Level 2

Verified Organization

Legal entity confirmed — LLC, AB, Corporation, Foundation.

Level 3

Regulated Institution

Licensed organization — banks, insurers, public authorities.

Level 4

Critical Infrastructure

National-level systems — central banks, tax agencies, land registries.

Level 5

Root Trust Authority

Protocol-level trust anchors — Svea Ark Foundation, National Root Authorities.

§ 04Identity Categories

Human Identity

Represents a natural person.

}

Organization Identity

Represents legal entities.

organization identityapplication/json

{
  "type": "organization",
  "legal_name": "Svea Ark Capital AB",
  "country": "SE",
  "registration": "556XXXXXX"
}

Foundation Identity

Represents trusts and foundations.

foundation identityapplication/json

{
  "type": "foundation",
  "name": "Svea Ark Foundation",
  "jurisdiction": "LI"
}

Government Identity

Represents public authorities.

  "country": "SE"
}

Agent Identity

Represents autonomous software.

agent identityapplication/json

{
  "type": "agent",
  "agent_name": "Treasury Agent",
  "version": "1.0"
}

§ 05Institutional Passport

Svea Ark introduces the Institutional Passport — a digital identity document.

It contains identity, jurisdiction, public keys, capabilities, trust score, attestations, and certification level.

institutional passportapplication/json

{
  "passport_id": "SAP-001",
  "entity": "Svea Ark Capital",
  "trust_level": "institutional"
}

Agent Passports

AI agents receive dedicated passports.

agent passportapplication/json

{
  "agent_id": "treasury_agent",
  "owner": "Svea Ark",
  "capabilities": [
    "PAYMENTS",
    "TREASURY"
  ]
}

§ 06Trust Scores & Grades

Every participant receives a dynamic trust score from 0 to 100, computed from security events, audit results, successful operations, human overrides, regulatory findings, certification status, and protocol violations.

trust scoreapplication/json

{
  "score": 96,
  "grade": "A+"
}

A+

95–100

90–94

80–89

70–79

60–69

Below 60

§ 07Attestation Framework

Trust is established through attestations — signed statements.

“Bank X is a regulated institution.” — Signed by: Financial Authority.

attestationapplication/json

{
  "issuer": "Financial Authority",
  "subject": "Bank X",
  "claim": "regulated_bank",
  "issued": "2026-01-01"
}

§ 08Public Key Infrastructure

All identities possess a public key, private key, certificate, and trust chain.

Mandatory Algorithms

Ed25519
ECDSA P-256
SHA-256
TLS 1.3

Optional Algorithms

Post-Quantum Signatures
Threshold Signatures
Multi-party Signing
Hardware-backed Keys

Hardware Security

Institutional systems should support YubiKey, FIDO2, TPM, Secure Enclave, and HSM.

§ 09Federation & Jurisdiction

Identity may be recognized across jurisdictions without requiring re-registration.

Swedish Bank ⇄ German Regulator ⇄ US Institution

jurisdictionapplication/json

{
  "country": "SE",
  "jurisdiction": "EU",
  "frameworks": [
    "GDPR",
    "PSD3"
  ]
}

§ 10Root Trust Network

Svea Ark defines Institutional, Agent, Foundation, and Government Certificate Authorities. Top-level authorities form the Svea Ark Root Trust Network — responsible for certificate issuance, revocation, security advisories, governance, and protocol enforcement.

§ 11Revocation

Trust must be removable. Certificates may be revoked for fraud, security breach, regulatory violations, compromise, or suspension.

revocationapplication/json

{
  "certificate": "cert_123",
  "status": "revoked",
  "reason": "security_compromise"
}

§ 12Identity Lifecycle

Stage 1

Registration

Stage 2

Verification

Stage 3

Certification

Stage 4

Operation

Stage 5

Monitoring

Stage 6

Revocation

§ 13Autonomous Agent Governance

Every AI agent must possess an owner, responsible authority, version, audit record, trust score, and risk classification.

Risk Levels

Low
Medium
High
Critical
Systemic

Human Oversight Requirements

Critical decisions require human approval — large payments, corporate restructuring, foundation asset transfers, government filings, cross-border transfers.

§ 14Identity Resolution Service

GET /v1/identity/resolve

requestapplication/json

{
  "id": "agent_001"
}

responseapplication/json

{
  "name": "Treasury Agent",
  "owner": "Svea Ark",
  "trust_score": 98
}

§ ∞Future Vision

Identity should become portable, cryptographic, jurisdiction-aware, institutional, machine-readable, and agent-compatible.

Identity becomes infrastructure. Trust becomes programmable. Institutions become interoperable.
