Abstract
Systems and methods for fuel dispenser security are disclosed herein. In some embodiments, a user seeking access to a protected function of the fuel dispenser is presented with a challenge that is encrypted using a secret key that is unique to the fuel dispenser. To access the secured function, the user must obtain a session password from a server which authenticates the user, decrypts the challenge using a counterpart of the secret key, determines whether the user is authorized to access the secured function, and returns the session password extracted from the challenge only when the user is authorized. The server can thus control access to certain fuel dispenser functions according to a set of user access privileges. The challenge can also include additional information which can be used by the fuel dispenser and/or by the server to store a log of access activity.
