The emerging build-ups of charging station infrastructures require sufficiently secure and economic authentication protocols. Existing protocols for the purpose of authenticating a customer against a charging station have the inherent disadvantage that they expect a network connection to the management system, produce a communication overhead, or might reveal sensitive customer data depending on the protocol. The protocol, provided by us, enables a multiple-operator customer-to-charging station authentication system. The particularity of the protocol is that it does not require a permanent network connection between charging stations and a corresponding management system, reduces the communication overhead between the involved entities, and protects sensitive customer data at a high rate.
