Described herein are techniques for providing authorization of vehicle charging requests in a manner that limits losses to unauthorized parties. Such techniques may comprise receiving, from a charging station, a request to access power resources, the request related to an electric vehicle in proximity of the charging station, providing, to the electric vehicle, a dynamic verification value to be used in authentication of the electric vehicle, and receiving, from the electric vehicle, a transformed version of the dynamic verification value generated by the electric vehicle. The techniques may further comprise independently generating, based at least in part on the dynamic verification value, an expected verification value, and determining whether to authorize the request based on a determination as to whether the transformed version of the dynamic verification value matches the expected verification value.
