|
|
echo "• Session-based authentication with 72-hour persistence"
|
|
echo "• Token refresh mechanism (up to 10 refreshes)"
|
|
echo "• Network change detection and logging"

echo "1. SMART RE-AUTHENTICATION TRIGGERS:"
|
|
echo " ✓ Network IP change detected (5G ↔ WiFi)"
|
|
echo " ✓ Device standby > 30 minutes"
|
|
echo " ✓ Multiple failed authentication attempts"
|
|
echo " ✓ Suspicious user agent changes"
|
|
echo " ✓ Geographic location changes (if available)"

echo "2. PROGRESSIVE SECURITY LEVELS:"
|
|
echo " • Level 1: Standard session refresh (current)"
|
|
echo " • Level 2: Challenge-response with existing secret"
|
|
echo " • Level 3: Full re-authentication required"

|
|
echo "3. IMPLEMENTATION STRATEGY:"
|
|
echo " • HTTP 401 Unauthorized with WWW-Authenticate header"
|
|
echo " • XEP-0363 compliant re-authentication flow"
|
|
echo " • Client-side automatic secret renewal"
|
|
echo " • Transparent user experience for trusted scenarios"

echo "4. SECURITY BENEFITS:"
|
|
echo " • Prevents token hijacking during network transitions"
|
|
echo " • Mitigates risks from device theft/loss"
|
|
echo " • Ensures fresh credentials after standby"
|
|
echo " • Maintains zero-configuration user experience"

|
|
echo "🎯 RECOMMENDED IMPLEMENTATION:"
|
|
echo "• Network change: Challenge-response (Level 2)"
|
|
echo "• Standby > 30min: Full re-auth (Level 3)"
|
|
echo "• Same network: Standard refresh (Level 1)"
