As electric vehicles (EVs) become increasingly prevalent, the demand for secure public charging infrastructure is growing. These charging stations, while essential, are vulnerable to cyber threats, particularly as they evolve to become more digitally connected.
Autocrypt, a leading South Korean automotive cybersecurity firm, has teamed up with eMobi, a U.S.-based e-mobility company, to bolster the security of AI-integrated EV charging stations. Their collaboration aims to address the cybersecurity risks inherent in this complex ecosystem by developing a secure communication framework.
Revolutionizing EV Charging with Plug & Charge Technology
Plug & Charge technology is designed to streamline the charging process by enabling automated communication between EVs and the charging infrastructure. This technology eliminates the need for external identification during billing, relying instead on cryptographic tools to secure communication channels.
eMobi currently operates over 120,000 connected charging ports, all of which issue digital certificates to authenticated users to safeguard the network. Their AI-driven systems enhance data processing capabilities, positioning eMobi as the largest AI-enabled roaming hub in North America. Through its partnership with Autocrypt, eMobi has established the first Plug & Charge ecosystem headquartered in the U.S., adhering to stringent U.S. data laws to ensure a robust and secure public charging network.
The integration of Autocrypt’s encryption technology into eMobi’s network allows EV drivers to securely charge their vehicles at any station. The system automatically identifies the vehicle and securely processes the payment, ensuring a seamless and safe user experience.
Cybersecurity Risks in AI-Integrated Charging Systems
While AI integration and software advancements offer numerous benefits, they also introduce new vulnerabilities. Public EV charging stations, especially those utilizing outdated, non-encrypted protocols, are prime targets for cyberattacks. Without proper security measures, hackers could exploit these systems to steal sensitive information, such as credit card details and personal data, or even inject malware into the network. This underscores the importance of robust cybersecurity in the digitally connected EV charging ecosystem.
Autocrypt’s Solution for Secure Plug & Charge Infrastructure
Autocrypt’s Plug & Charge protocol, now implemented within eMobi’s charging network, mitigates the cybersecurity risks associated with non-encrypted protocols. The system automatically verifies the driver’s identity by exchanging the vehicle’s digital certificate with the charger’s certificate. These exchanges are fully encrypted and validated through a public key infrastructure system, eliminating the need for drivers to manually input payment information.
Complying with ISO-15118 standards for vehicle-to-grid communication, the protocol also supports the Open Charge Point Protocol (OCPP) to authenticate contracts between the charging station management system (CSMS) and mobility operators (MO). Additionally, the CSMS enables charge point operators (CPOs) to monitor and manage multiple public charging stations, overseeing operations and billing in real-time.
Adapting to the Growing Demand for Public Charging
As the use of public EV charging stations continues to rise, there is a pressing need for user-friendly and secure infrastructure. Smart, digitally connected systems like Plug & Charge are crucial in meeting this demand, offering a seamless payment experience for users. With local networks ensuring higher levels of data security, Autocrypt and eMobi’s partnership is a significant step forward in the evolution of public EV charging infrastructure.
