Abstract: A method for secure communication between an initiator and a recipient is provided that includes sending to the recipient by the initiator a command packet, the command packet including a randomly generated time offset designating a time window in which the initiator expects to receive a response packet from the recipient, and receiving by the initiator in response to the command packet a response packet from the recipient, the response packet including a randomly generated time offset designating a time window in which the recipient expects to receive a subsequent command packet from the initiator.
