    Abstract: Logic may implement observation layer intrusion detection systems (IDSs) to combine observations by intrusion detectors and/or other intrusion detection systems. Logic may monitor one or more control units at one or more observation layers of an in-vehicle network, each of the one or more control units to perform a vehicle function. Logic may combine observations of the one or more control units at the one or more observation layers. Logic may determine, based on a combination of the observations, that one or more of the observations represent an intrusion. Logic may determine, based at least on the observations, characteristics of an attack, and to pass the characteristics of the attack information to a forensic logging system to log the attack or pass the characteristics of the attack to a recovery system for informed selection of recovery procedures. Logic may dynamically adjust a threshold for detection of suspicious activity.

    Abstract: Systems, methods, computer program products, and apparatuses for low latency, fully reconfigurable hardware logic for ensemble classification methods, such as random forests. An apparatus may comprise circuitry for an interconnect and circuitry for a random forest implemented in hardware. The random forest comprising a plurality of decision trees connected via the interconnect, each decision tree comprising a plurality of nodes connected via the interconnect. A first decision tree of the plurality of decision trees comprising a first node of the plurality of nodes to: receive a plurality of elements of feature data via the interconnect, select a first element of feature data, of the plurality of elements of feature data, based on a configuration of the first node, and generate an output based on the first element of feature data, an operation, and a reference value, the operation and reference value specified in the configuration of the first node.

    Abstract: A method comprises receiving an image of an update for a software module, a rate parameter, an index parameter, and a public key, generating a 32-byte aligned string, computing a state parameter using the 32-byte aligned string, generating a modified message representative, computing a Merkle Tree root node, and in response to a determination that the Merkle Tree root node matches the public key, forwarding, to a remote device, the image of the update for a software module, the state parameter; and the modified message representative.

    Abstract: A data processing system that provides for active prevention of masquerading attacks comprises a microcontroller, a transceiver, and an active attack prevention module (AAPM) in communication with the microcontroller and the transceiver. The microcontroller enables the data processing system to operate as a node in a vehicle control system (VCS). The transceiver enables the node to communicate with a local area network (LAN) of the VCS. The AAPM enables the node to monitor the LAN for messages. In response to detecting a message on the LAN, the AAPM automatically determines whether the message falsely identifies the node as a source, based on a value in an identifier field in the message. In response to determining that the message falsely identifies the node as the source, the AAPM automatically takes at least one remedial action to neutralize the message. Other embodiments are described and claimed.
