  • Method to mitigate voltage based attacks on key agreement over controller area network (CAN)
    Patent number: 10958680
    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.
    Type: Grant

  • Method to mitigate transients based attacks on key agreement schemes over controller area network
    Patent number: 10554241
    Abstract: 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.
