    Abstract: Systems and techniques for securing vehicle privacy in a driving infrastructure are described herein. A vehicle may contact a group identification (ID) issuer to register itself. A group ID may be received from the group ID issuer to indicate acceptance as a member. The vehicle may then contact the driving infrastructure to attach to the driving infrastructure using the group ID to identify the vehicle. In response, the vehicle receives an attachment ID from the driving infrastructure. Here, the attachment ID is used to secure communications between the vehicle and the driving infrastructure.

    Abstract: In one example a prover device comprises one or more processors, a computer-readable memory, and signature logic to store a first cryptographic representation of a first trust relationship between the prover device and a verifier device, the first cryptographic representation based on a pair of asymmetric hash-based multi-time signature keys, receive an attestation request message from the verifier device, the attestation request message comprising attestation data for the verifier device and a hash-based signature generated by the verifier device, and in response to the attestation request message, to verify the attestation data, verify the hash-based signature generated by the verifier device using a public key associated with the verifier device, generate an attestation reply message using a hash-based multi-time private signature key and send the attestation reply message to the verifier device. Other examples may be described.

    Abstract: Disclosed herein are mobile device distribution methods and apparatuses. In embodiments, a system for managing cryptographic exchanges between devices capable of operating in accord with the Wireless Access Vehicular Environment (WAVE) functionality may comprise a device operable in at least a first environment in which the device is configured to: receive a first message with an associated first certificate chain; and add a second certificate chain associated with the device to a second message. The device may further determine if the first certificate chain includes an unknown certificate, and if so, set a flag associated with the second message; as well as determine if all certificates in the first certificate chain are known, and if so, check if message has the set flag, and if the flag is set, then unset the flag; and send the second message. Other embodiments may be disclosed and claimed.

    Abstract: Various embodiments are generally directed to providing authentication and confidentiality mechanisms for message communication over an in-vehicle network. For example, authentication data associated with a communicating node may be transmitted over the network by encoding different predefined voltage levels on top of the message bits of the message being communicated. Different voltage levels may represent different encodings, such as a bit-pair or any bit combination of the authentication data. In a further example, messaging confidentiality between at least two communicating nodes may be achieved by pseudo-randomly flipping, or scrambling, the dominant and recessive voltages of the entire message frame at the analog level based on a pseudo-random control bit sequence.
