Secure wireless power access protocol suited for implementing levels of service in public and private environments

A computer program product for controlling a wireless transfer of electric power from a transmitter to a receiver, the transmitter having at least one transmitter processor circuit and at least one transmitter antenna circuit, the computer program product comprising:

• a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions readable by the at least one processor circuit to cause the at least one processor circuit to perform a method comprising:
• converting, using the at least one transmitter processor circuit, an electric power signal to an electromagnetic field (EMF);
• associating, using the at least one transmitter processor circuit, each of a plurality of keys with one of a plurality of operating frequencies, and storing the plurality of keys associated with the plurality of operating frequencies in a table;
• selecting, using the at least one transmitter processor circuit, one of the plurality of operating frequencies stored in the table as an active operating frequency, wherein the active operating frequency is assigned as the current operating frequency of the transmitter antenna circuit, and wherein the key associated with the active operating frequency is assigned as an active key;
• wirelessly transmitting to the receiver, using the at least one transmitter antenna circuit, the EMF at the active operating frequency;
• and
• wirelessly transmitting to the receiver, using the at least one transmitter antenna circuit, the table and an identification of the active key.
