Mahmoud Saad is a Principal Automotive Cybersecurity Engineer with over five years of experience securing connected vehicles and embedded systems. He specializes in cryptographic key management, ISO/SAE 21434 and UN R155 compliance, and OEM–supplier security alignment, with a strong focus on real‑world automotive production and lifecycle risks.
With a background in embedded systems engineering, he brings hands‑on experience with microcontrollers, HSMs, secure boot, PKI, and in‑vehicle communication protocols, bridging practical engineering constraints with regulatory and process requirements. His focus is on real‑world security failures arising from production practices, supply‑chain trust boundaries, and long vehicle lifetimes that directly impact fleet‑level safety.

From Entropy to Decommissioning: Cryptographic Key Management Strategies Across the Automotive Supply Chain.
Automotive cryptographic key management presents challenges fundamentally different from enterprise IT, driven by heterogeneous ECUs, multi‑tier supply chains, and vehicle lifetimes exceeding two decades. This paper analyzes cryptographic key management as a lifecycle‑coupled system spanning entropy generation, factory provisioning, secure storage, rotation and revocation, and decommissioning. It examines how alignment decisions between OEMs, Tier‑1 suppliers, and silicon vendors shape long‑term security outcomes and how early choices silently constrain or prevent recovery years later. Using real automotive failure modes—such as mis‑provisioning, revocation latency, irreversible trust anchors, and salvage‑yard exposure—the paper shows why many vehicle security incidents originate at production and manifest only in the field. The work emphasizes system‑level, process‑aware design over compliance‑driven or phase‑local controls.
