Abstract: Embodiments may include systems and methods for authenticating a message between a transmitter and a receiver. An apparatus for communication may include a transmitter to transmit a message to a receiver via a physical channel coupling the transmitter and the receiver. The message may be transmitted via a plurality of transmission voltage levels varied from a plurality of nominal voltage levels on the physical channel. The transmitter may include a voltage generator to generate the plurality of transmission voltage levels varied in accordance with a sequence of voltage variations from the plurality of nominal voltage levels for the message. The sequence of voltage variations may serve to authenticate the message between the transmitter and the receiver. Other embodiments may be described and/or claimed.

Abstract: In an automated method for providing driving assistance, an electronic control unit (ECU) of a first driving assistance system of a first vehicle receives local object information from at least one sensing component of the first driving assistance system. The first driving assistance system automatically detects external objects outside of the first vehicle, based on the local object information received from the at least one sensing component. The first driving assistance system also receives a reported object list (ROL) from a second vehicle, wherein the ROL describes objects detected by a second driving assistance system in the second vehicle. The first driving assistance system also affects operation of the first vehicle, based on (a) the external objects detected by the first vehicle and (b) the ROL from the second vehicle. Other embodiments are described and claimed.

IPC: H04L9/40

Abstract: Techniques to perform time recovery from attacks on delayed authentication in a time synchronized network are described. One embodiment comprises a method for decoding time information and a message authentication code (MAC) from a time message, the time information to synchronize a local clock for a device to a network time of a time synchronized network (TSN), and the MAC to authenticate the time message, determining whether the time message is authentic using the MAC, discarding the time information when the time message is not authentic, performing a bounded search to identify authentic time information using the MAC, and passing the authentic time information to a clock manager to synchronize the local clock to the network time of the TSN when the authentic time information is identified. Other embodiments are described and claimed.

Abstract: Techniques include a method, apparatus, system and computer-readable medium to detect, quantify and localize attacks to enhance security for time-synchronized networking. Embodiments include a diagnostic stream producer to produce diagnostic information providing evidence of a timing attack on a node of a time-synchronized network. Embodiments include a diagnostic stream consumer to consume diagnostic information, analyze the diagnostic information, and determine whether a node is under a timing attack. Other embodiments are described and claimed.

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.
