摘要
A method for operating at least one node connected to a shared communication medium reduces or eliminates the ability of an adversary node to identify the at least one node based on transient signal characteristics of a signal that the at least one node generates when transmitting a bit through the shared communication medium. The method includes adjusting, with a controller in a first node, an impedance of a variable impedance circuit in the first node to a first impedance level that the controller determines randomly, the variable impedance circuit in the first node being connected to an output of a transceiver in the first node and to a shared communication medium, and transmitting, with the transceiver, a first data bit through the shared communication medium with the variable impedance circuit producing the first impedance level.
