SDIS Quick Start Guide

Snapshot guidance: this document contains both currently wired endpoints and forward-looking flows. Verify live behavior against icn/crates/icn-gateway/src/api/sdis/mod.rs and docs/sdis/SDIS_STATUS.md.

🚀 Getting Started with SDIS

SDIS (Secure Distributed Identity System) enables secure multi-device identity management and recovery for ICN.

For End Users

Enrolling a New Device

1. On your NEW device:

   • Open Pilot UI
   • Navigate to "Identity" → "Enroll Device"
   • Enter your root DID
   • Choose a device name
   • Click "Start Enrollment"

2. Transfer the challenge:

   • Scan the QR code with your existing device, OR
   • Copy/paste the challenge code

3. On your EXISTING device:

   • Open enrollment approval page
   • Paste challenge (if not scanned)
   • Click "Approve Enrollment"

4. Back on NEW device:

   • Wait for approval confirmation
   • ✅ Device is now enrolled!

Adding Recovery Anchors

Why? Recovery anchors let you recover your identity if you lose all devices.

1. Open Pilot UI → "Identity" → "Recovery Anchors"
2. Click "Add Anchor"
3. Choose type:
   • Device: Another device you own
   • Contact: A trusted friend's device
4. Enter label (e.g., "My Phone")
5. Paste the public key
6. Click "Add Anchor"

Best Practice: Add at least 2-3 anchors (mix of devices and contacts).

Recovering Your Identity

If you lose all your devices:

1. On a new device, open Pilot UI
2. Navigate to "Identity" → "Recover Identity"
3. Enter your root DID
4. The system will notify your recovery anchors
5. Ask your trusted contacts to approve on their devices
6. Once threshold is met (e.g., 2 of 3), recovery completes
7. ✅ Your identity is restored!

For Stewards

Steward Dashboard

Stewards review and vouch for identity enrollments. Access the dashboard at:

• Web: http://<gateway-host>:30030/steward-dashboard.html
• Mobile: CoopWallet app → Home → Steward Dashboard

Reviewing Enrollments

1. Open the Steward Dashboard
2. View Pending tab for enrollments awaiting vouch
3. Click an enrollment to see details:
   • Identity name and coop
   • Current verification level
   • Expiration time
4. Choose to Vouch or Reject

Vouching for an Identity

1. Select a pending enrollment (must be Level 1+)
2. Click Vouch
3. Enter your verification statement (how you verified the person)
4. Confirm the verification checklist:
   • ✅ Identity verified in person or via video call
   • ✅ Person matches their stated identity
   • ✅ No suspicious behavior observed
5. Submit your vouch

Rejecting an Enrollment

1. Select a pending enrollment
2. Click Reject
3. Enter the rejection reason
4. Confirm rejection

API Examples

Enroll a Device

# Step 1: Request enrollment
curl -X POST http://localhost:8080/v1/sdis/enrollment/start \
  -H "Content-Type: application/json" \
  -d '{
    "identity_name": "alice",
    "coop_id": "my-coop"
  }'

# Response:
{
  "enrollment_id": "enr_abc123",
  "verification_code": "ABCD-1234",
  "expires_at": "2026-02-12T12:34:56Z"
}

# Step 2: Steward records a vouch
curl -X POST http://localhost:8080/v1/sdis/vouch/enr_abc123 \
  -H "Content-Type: application/json" \
  -d '{
    "vouch_statement": "I can verify this member identity."
  }'

# Response:
{
  "status": "vouched",
  "enrollment_id": "enr_abc123",
  "level": 2
}

# Step 3: Check enrollment status
curl http://localhost:8080/v1/sdis/status/enr_abc123

# Response:
{
  "enrollment_id": "enr_abc123",
  "status": "ready_for_completion",
  "level": 2
}

Add Recovery Anchor

curl -X POST http://localhost:8080/v1/sdis/anchor/devices/add \
  -H "Content-Type: application/json" \
  -d '{
    "anchor_id": "anc_def456",
    "device_name": "My Phone",
    "device_pubkey": "MCowBQYDK2VwAyEA..."
  }'

# Response:
{
  "device_id": "dev_123",
  "device": {
    "device_name": "My Phone"
  }
}

List Anchors

curl http://localhost:8080/v1/sdis/anchor/anc_def456/devices

# Response:
{
  "devices": [
    {
      "device_id": "dev_123",
      "device_name": "My Phone"
    }
  ]
}

JavaScript SDK

The SDK surface evolves independently; treat the snippet below as conceptual and verify against current sdk/typescript exports.

import { ICNClient } from '@icn/sdk';

const client = new ICNClient({ baseURL: 'http://localhost:8080' });

// Enroll device
const enrollment = await client.sdis.enroll({
  rootDid: 'did:icn:z6Mk...',
  deviceDid: 'did:icn:z6Mk...',
  deviceLabel: 'My Laptop',
  devicePubkey: 'MCowBQYDK2VwAyEA...'
});

console.log('Challenge:', enrollment.challenge);

// Approve enrollment
await client.sdis.approveEnrollment(enrollment.enrollmentId, {
  signature: signedChallenge
});

// Add anchor
const anchor = await client.sdis.addAnchor({
  anchorType: 'device',
  label: 'My Phone',
  pubkey: 'MCowBQYDK2VwAyEA...'
});

// List anchors
const anchors = await client.sdis.listAnchors();

For Operators

Deployment

SDIS is automatically deployed with the ICN Gateway:

cd deploy/k8s
make build deploy

Configuration

Edit config/icn.toml:

[sdis]
# Challenge expiration (seconds)
challenge_ttl = 300

# Recovery threshold (N of M anchors required)
recovery_threshold = 0.67  # 67% = 2 of 3

# Maximum enrollments per identity
max_devices = 10

# Proof expiration (optional, 0 = never)
proof_expiration = 0

Monitoring

Key metrics (Prometheus):

sdis_enrollments_total
sdis_enrollments_approved
sdis_enrollments_failed
sdis_anchors_total
sdis_anchors_revoked
sdis_recovery_initiated
sdis_recovery_completed

Troubleshooting

Problem: Challenge expired
Solution: Re-initiate enrollment (challenges last 5 minutes)

Problem: Signature verification failed
Solution: Ensure device_pubkey matches the key used to sign

Problem: Insufficient recovery anchors
Solution: User needs to add more anchors before recovery

Security Best Practices

For Users

1. ✅ Add 2-3 recovery anchors minimum
2. ✅ Mix device and contact anchors
3. ✅ Revoke anchors for lost/stolen devices immediately
4. ✅ Use descriptive labels for devices
5. ✅ Review anchor list monthly

For Developers

1. ✅ Always verify Ed25519 signatures
2. ✅ Enforce challenge expiration
3. ✅ Rate-limit enrollment attempts
4. ✅ Log all SDIS operations
5. ✅ Never transmit private keys

For Operators

1. ✅ Monitor enrollment success rate
2. ✅ Alert on unusual recovery patterns
3. ✅ Backup proof chains regularly
4. ✅ Set appropriate thresholds
5. ✅ Provide user support channels
