Autonomous Driving Vehicle Security
Keypair's HSM enables both in-vehicle security and vehicle-to-everything (V2X) communication security.
Security Challenges of the Connected Car Era
Autonomous Driving & Security. Autonomous vehicles connect dozens of ECUs over an internal network and exchange data with external vehicles and infrastructure via V2X communication. Each communication path is a potential attack vector, making hardware-based security essential.
HSM-Based Protection. Keypair's HSM (Hardware Security Module) is integrated into in-vehicle ECUs and gateways to ensure the integrity of control commands and encrypt V2X communication channels.
Dual Security Architecture. Simultaneous support for in-vehicle network security and external V2X communication security provides a comprehensive security framework for autonomous driving environments.
Key Security Threats
- Vehicle control command tampering via CAN Bus Hacking
- Fake traffic information injection via V2X communication spoofing
- Malware injection via OTA update tampering
- Unauthorized access via vehicle authentication bypass

Security Provided by the HSM
Hardware security features designed exclusively for autonomous vehicles
In-Vehicle Security
Encrypts communication data within the in-vehicle network—including ECUs and gateways—to prevent unauthorized access and control command tampering.
V2X Communication Security
Encrypts vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication to ensure safe data exchange in autonomous driving environments.
Device Authentication
Builds a trust framework using HSM-based hardware authentication so only authorized vehicles and infrastructure can participate in communication.
Secure Key Management
Securely stores and manages vehicle cryptographic keys inside the HSM to fundamentally prevent key leakage and cloning.
Multi-Layer Security
From the vehicle interior to external infrastructure — layer-by-layer security
ECU Security
HSM is embedded in critical ECUs—engine, brakes, steering—to guarantee the integrity of control commands.
Gateway Security
Only authenticated communication is allowed through the in-vehicle network gateway, blocking external intrusions.
V2V Security
Direct vehicle-to-vehicle communication is encrypted to prevent traffic information tampering and spoofing attacks.
V2I Security
Communication with traffic signals and road infrastructure is protected to ensure data reliability for autonomous driving decisions.
