Overview

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

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.

Layers

Multi-Layer Security

From the vehicle interior to external infrastructure — layer-by-layer security

01

ECU Security

HSM is embedded in critical ECUs—engine, brakes, steering—to guarantee the integrity of control commands.

02

Gateway Security

Only authenticated communication is allowed through the in-vehicle network gateway, blocking external intrusions.

03

V2V Security

Direct vehicle-to-vehicle communication is encrypted to prevent traffic information tampering and spoofing attacks.

04

V2I Security

Communication with traffic signals and road infrastructure is protected to ensure data reliability for autonomous driving decisions.
