Hubject and Penta Security Cooperate to Provide First Global Cross Certification for most Secure ISO 15118 based EV Charging

BERLIN, GERMANY | November 14, 2019

  • Hubject and Penta Security, both Vehicle to Grid Root Certificate Authorities (V2G Root CAs), will complete a direct cross-certification to enable a global use of the existing solutions
  • The cross-certification eases the global rollout of ISO 15118 based Plug&Charge solutions, enabling interested innovators to effectively choose between the V2G Root CA of Hubject and Penta Security

Hubject and Penta Security today announced their co-operation to enable standardized secure communication between electric vehicles and charging stations. The international standard ISO 15118 is mostly known for the application of the most secure, automated and seamless charging and payment processes for electric vehicles, Plug&Charge. The security of ISO 15118 is based on the automated comparison of stored digital certificates.

The certificates originate from a central, highest certification authority: the Vehicle to Grid Root Certification Authority or V2G Root CA. Hubject and Penta Security are both V2G Root CAs and will now certify each other. Hubject’s V2G Root CA serves as a foundation of trust and provides interoperability by cross certifying with the V2G Root CA of the Korean market leader for secure EV Charging, Penta Security. This means that both partners can process not only the validated authentication data of their own Root CA but also that of the other partner. This way, Hubject, and Penta Security provide a joint approach to support companies active in relevant EV Markets like Korea, Europe, and North America.

“Security in EV charging is an infrastructure that allows more openness with improved control. Through this cross-certification realization, we are excited to present the basis for an unrestricted charging environment that provides convenience and accuracy throughout the entire charging and paying process,” said Seokwoo Lee, CEO and Founder at Penta Security, a leader in web, IoT, and data security with over a decade of experience in the connected car industry.

“We are working for globally open standards. This goes for security as well. Companies adopting the ISO 15118 standard, especially the Plug&Charge use case have now the security, that, whatever service provider they are choosing to work with, will be supported by the other Root CA operator so that there is no lock-in effect,” said Christian Hahn, CEO of Hubject, one of the global leaders of supporting companies on the topic of secure communication between electric vehicles and charging stations.
