Enabling Secure Interoperability Across OEM, CPO, and eMSP Networks
A global electric vehicle manufacturer needed to support ISO 15118-compliant Plug & Charge across its growing network of vehicles, charge points, and service providers. As EV adoption accelerated, the company required a unified trust infrastructure that could authenticate vehicles, chargers, and mobility service providers automatically — eliminating user friction while maintaining cryptographic control and compliance with international standards.
ISS Solution
ISS delivered its ChargeAuth platform — a production-grade, vehicle-to-grid (V2G) public key infrastructure built on the same Secure Credential Management System (SCMS) architecture trusted by leading automakers and state transportation agencies.
At the manufacturing level, ISS enabled secure certificate provisioning directly into vehicle controllers, ensuring every EV left the factory with a unique, verifiable identity.
For charging infrastructure, ISS provided CPO-facing interfaces and APIs to automate certificate enrollment, renewal, and revocation across distributed charging networks.
ISS also supported the customer’s e-Mobility Service Provider (eMSP) operations by integrating authentication services for Plug & Charge transactions, ensuring seamless roaming across partner networks.
Behind the scenes, all certificates, signing keys, and revocation lists are managed through FIPS 140-validated hardware security modules (HSMs) and 24/7 enterprise-grade infrastructure operated by ISS.
