Trust Framework — Cryptographically Verifiable AI Agent Identity

🔐 When an AI agent takes action in your systems, can you prove which agent did it?

Most AI security tools treat all agents as anonymous. When something goes wrong, you get logs saying “an AI made this request” — but no cryptographic proof of which agent, what it was authorized to do, or whether its behavior matched its intended role.

AegisGate Trust Framework changes this. Every agent gets a unique cryptographic identity. Every action is signed. Every attestation is independently verifiable. No server round-trip needed.

The Anonymous Agent Problem

Today’s AI deployments have a critical blind spot:

When incident response begins, you cannot cryptographically prove:

• Which specific agent took the action
• What capabilities that agent was authorized to use
• Whether the agent’s behavior matched its intended role
• Whether the logs themselves have been tampered with

This is compliance theater, not security.

The Trust Framework Solution

AegisGate Trust Framework provides four cryptographic guarantees:

1. Per-Agent ECDSA Identity

Every agent gets a unique ECDSA P-256 keypair at registration:

{
  "agent_id": "agent-copilot-dev-001",
  "public_key": "MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAE...",
  "registered_at": "2026-01-15T09:23:47Z",
  "fingerprint": "SHA256:7d8a9b2c4e5f6a1b3c4d5e6f7a8b9c0d"
}

Why this matters:

• No two agents share the same identity
• Public key is registered in a tamper-evident ledger
• Fingerprint allows human-verifiable identity confirmation
• Private key never leaves the agent’s secure enclave

2. Capability Contracts

Every agent operates under a signed capability contract that explicitly defines what it’s authorized to do:

{
  "agent_id": "agent-copilot-dev-001",
  "capabilities": ["code_suggestion", "file_read"],
  "restrictions": ["no_file_write", "no_network_call", "no_secret_access"],
  "issued_by": "platform-admin",
  "issued_at": "2026-01-15T09:23:47Z",
  "expires_at": "2027-01-15T09:23:47Z",
  "signature": "MEUCIQDvL..."
}

Enforcement:

• Platform enforces contracts at runtime (fail-closed)
• Agent cannot exceed authorized capabilities
• Contract violations trigger immediate trust score degradation
• Contracts are cryptographically signed — tamper-evident

3. Real-Time Trust Scoring

Every agent has a dynamic trust score (0-100) that updates in real-time based on:

Trust Score Actions:

Anomaly Detection:

• Sudden trust score drops trigger alerts
• Platform tracks rolling 30-day baselines
• Unusual access patterns (time, frequency, resource type) flagged

4. Signed Attestations

Every agent action produces a self-verifying attestation envelope:

{
  "attestation_id": "att-2026011509234701",
  "agent_id": "agent-copilot-dev-001",
  "action": "file_read",
  "resource": "/src/config/database.yml",
  "timestamp": "2026-01-15T09:23:47Z",
  "trust_score": 94,
  "payload_hash": "SHA256:a1b2c3d4e5f6...",
  "signature": "MEUCIQDvL8K9mN2pQ3rS4tU5vW6xY7zA8bC9dE0fG1hI2jK3lM4n"
}

Verification (no server round-trip):

# Anyone with the agent's public key can verify offline
openssl dgst -sha256 -verify agent-copilot-dev-001.pub \
  -signature attestation.sig \
  attestation.json

Output: Verified OK ✅

Why this matters:

• Auditors can verify attestations without accessing your Platform instance
• Evidence is admissible in regulatory proceedings (cryptographic integrity)
• No dependency on AegisGate servers — attestations are self-contained
• Tamper-evident: any modification invalidates the signature

Use Cases by Industry

Banking & Financial Services

Problem: Regulators require proof of who (or what) accessed customer data.

Trust Framework Solution:

• Every AI agent accessing customer PII has a cryptographic identity
• Capability contracts enforce “read-only” for non-transactional agents
• Signed attestations provide audit trail for FFIEC, SOX, GLBA exams
• Trust score degradation triggers automatic escalation

Compliance Mappings:

• FFIEC CAT: PR.AM-3 (Asset inventory), PR.DS-5 (Data access audit)
• SOX: Section 404 (Internal controls over financial reporting)
• GLBA: Safeguards Rule (21 CFR Part 314)

Healthcare

Problem: HIPAA requires audit controls for PHI access. AI agents accessing patient records must be accountable.

Trust Framework Solution:

• Agents accessing EHR systems have unique cryptographic identities
• Capability contracts limit agents to minimum necessary PHI
• Signed attestations provide tamper-evident audit logs
• Trust score drops trigger HIPAA breach assessment workflow

Compliance Mappings:

• HIPAA Security Rule: §164.312(b) (Audit controls), §164.308(a)(1)(ii)(D) (Information system activity review)
• HITECH Act: Breach notification requirements

Government & Defense

Problem: NIST, FedRAMP, DoD IL5 require cryptographic identity for all system actors.

Trust Framework Solution:

• ECDSA P-256 meets FIPS 186-4 digital signature requirements
