Abstract: Time recovery techniques are described. A method comprises receiving messages from the first device by the second device in the first network domain, the messages to comprise time information to synchronize a first clock for the first device and a second clock for the second device to a network time, determining the second clock is to recover the network time for the second device without new messages from the first device, retrieving a first set of timestamps previously stored for events in the first network domain using the network time from the second clock, retrieving a second set of timestamps previously stored for the events in the first network domain using a redundant time from a third clock, where the third clock is not synchronized with the first and second clocks, and recovering the network time using a regression model and the redundant time from the third clock.

Abstract: Systems, apparatuses, and methods to response to distinguish a ghost target from an actual target based on radar signals is provided. In particular, the disclosure provides an intrusion detection system adapted to receive radar signals and distinguish a potential ghost target from a legitimate target based on a signal to noise ratio of the radar signals and a range to the ghost target and the legitimate target.

Abstract: A method comprises fetching, by fetch circuitry, an encoded parity instruction comprising at least one opcode, a first source identifier for a first source, a second source identifier for a second source, a third source identifier for a third source, and a destination identifier for a destination, decoding, by decode circuitry, the encoded parity instruction to generate a decoded parity instruction; and executing, by execution circuitry, the decoded parity instruction to retrieve operands representing a first register from the first source, a second register from the second source, a third register from the third source, and an index from the third source, perform an XOR operation of four words of data from the first register and single word of data from the second register in a position represented by the index to generate a parity value, and store the parity value in a the first register in a position represented by the index.

Abstract: Systems, apparatuses, and methods to response to distinguish a ghost target from an actual target based on radar signals and ranges determined from the radar signals. In particular, the disclosure provides an intrusion detection system receiving ranges and velocities for targets detected based on radar signals, determining a potential ghost target from the received velocities and confirming the potential ghost target based on estimated ranges and perturbations of the vehicle speed.

Abstract: Systems, apparatuses, and methods to establish a mapping between message identifications for messages transmitted on a communication bus and electronic control units transmitting the messages is provided. In particular, retransmission of a low priority message onto the bus is forced such that the retransmitted low priority message overlaps with a higher priority message to determine whether the messages originated from the same ECU.

Abstract: Systems, apparatuses, and methods to identify an electronic control unit transmitting a message on a communication bus, such as an in-vehicle network bus, are provided. ECUs transmit messages by manipulating voltage on conductive lines of the bus. Observation circuitry can observe voltage signals associated with the transmission at a point on the in-vehicle network bus. A distribution can be generated from densities of the voltage signals. ECUs can be identified and/or fingerprinted based on the distributions.
