Industry Challenges

Large numbers of vehicles, ECUs, mobile devices, and roadside units make key and certificate lifecycle management increasingly complex

FOTA updates, digital keys, and other connected services depend on reliable authentication, digital signatures, and access authorization

Trust boundaries continue to expand across vehicles, cloud platforms, charging infrastructure, and roadside systems

Vehicle data is exposed to risks of disclosure, forgery, and tampering during collection, transmission, storage, and use

Collaboration across multiple organizations, platforms, and suppliers increases the complexity of unified cryptographic management and security auditing

Solution

By deploying HSMs in data centers, cloud platforms, or production systems, root keys, CA signing keys, firmware-signing keys, key-encryption keys, and service private keys can be protected within a hardware security boundary. The HSM provides centralized cryptographic services for PKI, KMS, code signing, key provisioning, and connected-vehicle platforms.

The solution supports key generation, protection, backup, rotation, and destruction, while providing cryptographic capabilities for certificate issuance and revocation, firmware signing, identity authentication, data encryption, and operational auditing. It helps organizations establish a trusted security framework covering vehicle production, delivery, operation, software updates, and decommissioning.

Key Applications

ECU Key Provisioning

Integrate HSMs with vehicle production and after-sales systems to securely generate, protect, and provision ECU keys and device certificates. This establishes trusted identities for vehicles and components while supporting subsequent key updates and certificate maintenance.

Secure FOTA Updates

Protect firmware-signing private keys and digitally sign update packages, enabling vehicles to verify software authenticity and integrity and preventing unauthorized or tampered software from being installed.

Digital Key

Protect backend key-issuance keys and service private keys, supporting the secure issuance, distribution, sharing, revocation, and access authorization of digital vehicle keys.

Plug & Charge

Protect root keys, CA signing keys, and service private keys within the V2G PKI, supporting the issuance, renewal, and management of charging certificates and enabling automated authentication and authorization between vehicles and the charging-service ecosystem.

V2X Security

Protect trust anchors and CA signing keys within the V2X PKI, supporting certificate issuance, renewal, and revocation for vehicles and roadside units and establishing a trusted vehicle-to-everything communication environment.

Core Benefits

Hardware-Based Key Protection

Reduce the risks of plaintext exposure, unauthorized export, and unauthorized use of critical cryptographic keys.

Unified Vehicle Trust Framework

Centrally manage cryptographic keys and digital certificates for vehicles, devices, applications, and service platforms.

Scalable Service Support

Support large-scale vehicle onboarding, certificate issuance, and high-volume cryptographic operations.

Compliance and Audit Support

Record key operations and cryptographic service logs to support automotive cybersecurity management and auditing.
