Key Management Infrastructure
Automotive KMI
End-to-end key lifecycle and provisioning management
Foundational Infrastructure for End-to-End Key Lifecycle Security
During vehicle manufacturing and deployment, each ECU and end entity within the vehicle must be secured using assigned cryptographic keys to ensure authenticated access and system integrity.
In cryptographic systems, key management is as critical as encryption itself. Given the scale, diversity and volume of keys required across the vehicle lifecycle, manual key management increases operational complexity and significant security risks.
Automotive KMI addresses these challenges by orchestrating PKI and key management across the entire vehicle lifecycle, while enabling cross-domain key architecture integration across OEM and supplier environments.
Automotive KMI Products
AutoCrypt® PKI issues and manages SSL/TLS digital certificates based on X.509 across Root, Sub, and Leaf CA structures, enabling secure user authentication. Built on UNECE R155 and ISO/SAE 21434 standards, it provides unified dashboard visibility and offers flexible deployment options from on-premise to SaaS.
Key generation and storage with AutoCrypt® KMS
AutoCrypt® KMS generates and manages cryptographic keys through a hardware-based architecture. Equipped with a hardware security module (HSM) that produces true random numbers (TRN), it provides heightened security for key generation and storage, compliant with ISMS(ISO/IEC 27001), PCI DSS, and certified to FIPS 140-2 Level 3.
Key distribution middleware with AutoCrypt® KeyLink
AutoCrypt® KeyLink enables secure key generation and distribution to vehicle ECUs through middleware integration within production environments. By verifying ECU data and serial numbers via manufacturing execution systems (MES), it prevents duplication and unauthorized provisioning.
How It Works
Automotive KMI enables end-to-end vehicle lifecycle security through a secure credential pipeline linking OEMs and suppliers. It orchestrates PKI and key management across diverse manufacturing environments, ensuring continuity of trust from vehicle production to in-field operation and long-term lifecycle governance.
Case Study
This case study demonstrates how Automotive KMI unified OEM backend systems, factory environments, and in-vehicle components under a single, integrated key management framework.
By orchestrating PKI and key operations across OEM and Tier 1 suppliers, it enables secure provisioning, injection, and lifecycle update workflows — ensuring continuity of trust from manufacturing through in-field vehicle operation. Optional modules, such as add-on ESF integration and customizable security configurations, were deployed to align with specific architecture and operational requirements.
