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: 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 may provide for technology that detects one or more non-compliant nodes with respect to a timing schedule, detects one or more compliant nodes with respect to the timing schedule, and identifies a malicious node based on positions of the one or more non-compliant nodes and the one or more compliant nodes in a network topography. The non-compliant node(s) and the compliant node(s) may be detected based on post-synchronization messages, historical attribute data and/or plane diversity data.

Abstract: Systems, apparatuses, and methods to response to detected attacks in an autonomous system based on context of the autonomous system are described. In particular, the disclosure provides an intrusion detection system receiving contexts and contracts dictating particular response guide rails from a higher level components or stack on the autonomous system. The intrusion detection system is arranged to respond to attacks according to the contract without intervention by the higher level components or stack.

Abstract: Systems, apparatuses, and methods to accelerate classification of malicious activity by an intrusion detection system are provided. An intrusion detection system can speculate on classification of labels in a random forest model based on temporary and incomplete set of features. Additionally, an intrusion detection system can classify malicious context based on a set of committed nodes in the random forest model.

Abstract: A computing node to implement a management entity in a CP-based network. The node including processing circuitry configured to encode an inquiry message requesting information on CPS capabilities. Response messages are received from a set of sensing nodes of a plurality of sensing nodes in response to the inquiry message. The response messages include the information on the CPS capabilities of the set of sensing nodes. A notification message indicating selecting of a sensing node as a sensing coordinator is encoded for transmission. Sensed data received in a broadcast message from the sensing coordinator is decoded. The sensed data including data associated with one or more non-V2X capable sensing nodes.

Abstract: Systems, apparatuses, and methods to mitigate effects of glitch attacks on a broadcast communication bus are provided. The voltage levels of the communication bus are repeatedly sampled to identify glitch attacks. The voltage level on the communication bus can be overdriven or overwritten to either corrupt received messages or correct received messages.
