ABSTRACT:
A method and system for secure communication and control in a fueling environment. In one aspect, the fueling environment with secure communication comprises a fuel dispenser and at least one node communicable coupled with the fuel dispenser. The fuel dispenser is operable to generate a first public key and a first private key associated with the fuel dispenser and publish the first public key within the fueling environment. The fuel dispenser is further operable to authenticate a particular one of the nodes using, at least in part, a second public key associated with the particular node and the first public and the first private keys. The fuel dispenser may then dynamically generate a run-time symmetric key using, at least in part, the first private key and the second public key and communicate data associated with the fueling environment to the authenticated node, with the data encrypted using the symmetric key.
