🛡️ UID Spoofing Mitigation Simulation

Extreme-Spartan Cognitive Industries Pvt. Ltd.

🔍 Threat Model

Spoofing attempts may include: - Cloning UID codes from QR/NFC overlays
- Replay attacks during OTA sync
- Unauthorized firmware injection
- UID substitution in audit logs

🔐 Mitigation Architecture

Layer Mechanism Purpose
UID Challenge Token Time-bound hash + salt Prevent replay attacks
TLS Handshake Mutual authentication Secure OTA channel
QR/NFC Signature ECC-based UID signing Field-level spoof resistance
UID Server Sync Challenge-response validation Centralized spoof detection
Audit Trail Hashing SHA256 + UID chain Tamper-proof logging
