ISO 15118 Security Implementation

Alefbits is your partner for the critical security implementation decisions of ISO 15118

Critical Implementation Decisions

While ISO 15118 establishes a comprehensive framework for EV charging security through transport-layer and application-layer requirements, it intentionally leaves several critical implementation decisions to automotive OEMs.

Our expertise is in embedded automotive software that bridges these implementation gaps. We help OEMs make and implement the critical security decisions that ISO 15118 doesn’t address, with specialized focus on certificate management, secure storage, and optimized cryptographic implementations.

As the implementers of our own ISO 15118 Communication Stack, we bring unparalleled expertise in charging communication security. Our hands-on experience developing and maintaining our CCM-EV product gives us deep insights into the real-world security challenges and optimal implementation approaches for automotive OEMs.

Certificate & Key Storage

ISO 15118 doesn’t specify how certificates and keys should be stored.

Storage Strategy
  • Secure storage options assessment
  • Memory-efficient certificate storage
  • HSM vs. Host based storage analysis
Integration Services
  • HSM software integration
  • Secure storage access mechanisms
  • Third-party Crypto stack integration
Certificate & Key Lifecycle

ISO 15118 doesn’t define how certificate chains should be provisioned or updated.

Implementation Strategy
  • Initial certificate provisioning
  • Certificate update mechanisms
  • Certificate revocation procedures
Complex Device Drivers
  • Secure certificate storage and retrieval
  • Certificate lifecycle management
  • Secure diagnostics for certificate operations
Cryptographic Operations

ISO 15118 doesn’t specify where cryptographic operations should be performed.

Host vs. HSM Implementation
  • Security vs. performance analysis
  • Cryptographic operation placement options
  • HSM vs. host-based solutions assessment
Implementation Services
  • Third-party Crypto stack integration
  • Cryptographic operation request handling for synchronous and asynchronous operations
  • Performance optimization
