A threat analysis of the vehicle-to-grid charging protocol ISO 15118

This work performs a security analysis of the vehicle-to-grid charging protocol ISO 15118 and presents various scenarios of how to compromise the availability of the charging service or the integrity, authenticity, or confidentiality of the communication on a protocol level. Furthermore, it analyzes processes related to the authentication, transfer of information, and the certification hierarchy for vulnerabilities, which could be used by an adversary to gain unfair advantage over the charging process and use it for his own self-interest, mostly harming legitimate users or other participants.
