Title: METHOD TO MITIGATE VOLTAGE BASED ATTACKS ON KEY AGREEMENT OVER CONTROLLER AREA NETWORK (CAN)
Abstract:
A method of operating at least one node in a communication network that uses a shared communication medium has been developed. The method includes adjusting, with a controller in a first node, a resistance of a first potentiometer in the first node to a first resistance level that the controller in the first node determines randomly, the first potentiometer 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 in the first node, a first data bit through the output that is connected to the shared communication medium with the first potentiometer producing the first resistance level.
