Some embodiments provide a system to protect an electric vehicle charging infrastructure. An electric vehicle charging site may receive AC power from a power grid and provide DC power to electric vehicles. The charging site may include a plurality of monitoring nodes each generating a series of current monitoring node values over time that represent a current operation of the electric vehicle charging infrastructure. A supply equipment communication controller may receive an access request from an access requestor associated with an electric vehicle, the access request being associated with a platform certificate. A secondary actor policy decision point at the charging site may evaluate the access requestor's identity and respond with an action message allowing high-level communication with the access requestor to proceed. Note that information associated with the current monitoring node values and/or the access request may be stored in a secure, distributed transaction ledger (e.g., an attestation blockchain).
