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: In one example an apparatus comprises a computer readable memory; and a signature module to generate a set of cryptographic keys for attestation of group member devices and a set of leaf nodes in a sub-tree of a Merkle tree corresponding to the set of cryptographic keys, forward the set of leaf nodes to a group manager device, receive, from the group manager device, a subset of intermediate nodes in the Merkle tree, the intermediate nodes being common to all available authentications paths through the Merkel tree for signatures originating in the sub-tree, and determine a cryptographic key that defines an authentication path through the Merkle tree, the authentication path comprising one or more nodes from the set of leaf nodes and one or more nodes from the intermediate nodes received from the group manager device. Other examples may be described.

Abstract: In one example an apparatus comprises signature circuitry to receive input variables comprising a value (X), a start index (i), a number of steps (s), a seed (SEED) and a memory address (ADRS) to store one or more context variables, and implement a loop for a multi-stage calculation of a Winternitz one-time signature (WOTS), wherein one or more WOTS hash functions are computed in each stage of the multi-stage calculation. Other examples may be described.

Abstract: Various embodiments are generally directed to techniques for providing improved privacy protection against vehicle tracking for connected vehicles of a vehicular network. For example, at least one road side unit may: identify a set of vehicles that require pseudonym changes and send an invitation for a pseudonym change event to each of the vehicles, determine at least a total number of the acceptances, determine whether the total number meets or exceeds a predetermined threshold number, send acknowledgement messages to the accepting vehicles if the threshold number is met, and form a vehicle group to coordinate the pseudonym change event during a privacy period. During the privacy period, the RSU and the vehicles may communicate with each other in a confidential and private manner via key-session-based unicast transmission, and coordinate transmission power and vehicle trajectory adjustments to maximize the benefits for safety and obfuscation for privacy.

Abstract: In one example an apparatus comprises a computer readable memory, a signature logic to generate a signature to be transmitted in association with a message, the signature logic to apply a hash-based signature scheme to the message using a private key to generate the signature comprising a public key, or a verification logic to verify a signature received in association with the message, the verification logic to apply the hash-based signature scheme to verify the signature using the public key, and an accelerator logic to apply a structured order to at least one set of inputs to the hash-based signature scheme. Other examples may be described.

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.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for anomaly detection and recovery. An apparatus to isolate a first controller in an autonomous vehicle includes a first controller to control a reference signal of the autonomous vehicle via a communication bus, a second controller to control the reference signal of the autonomous vehicle when the first controller is compromised, and a message neutralizer to neutralize messages transmitted by the first controller when the first controller is compromised, the neutralized messages to cause the first controller to become isolated from the communication bus.
