Securing the Information Infrastructure for EV Charging

We consider the functional and security requirements for the information exchanges in the infrastructure for EV charging being trialled in the Netherlands, which includes support for congestion management using the smart charging protocol OSCP. We note that current solutions do not provide true end-to-end security, even if all communication links are secured (for instance with TLS), as some data is forwarded between multiple parties. We argue that securing the data itself rather than just securing the communication links is the best way to address security needs and provide end-to-end security.
