Project: Embedded Module Authentication & Security
Implemented secure authentication for an on-field embedded module using hardware cryptography, protecting critical vehicle features against spoofing.
Project Overview
This project aimed to strengthen in-vehicle security by introducing hardware-level authentication between modules controlling safety-critical functions. The system verifies authenticity using a cryptographic handshake before enabling communication or feature activation.

Key Details / Outcomes
Spoofing Protection: Achieved secure HMAC-based challenge-response handshake between paired devices.
Low Latency Verification: Authentication completes under 10 ms per exchange.
Scalable Framework: Design can extend to multiple nodes using unique keys per module.
Challenges and Learnings
Secure key storage and protection against field tampering were major design concerns.
- Key protection — implemented on-chip secure element
- Timing sync — added nonce-based verification
- Integration — abstracted cryptographic driver layer for reuse
