    Abstract: A method for classifying a road surface being traversed by a vehicle. The method comprises receiving one or more electrical signals each representative of a vibration detected by a sensor carried by the vehicle. The method further comprises identifying, for at least one of the received electrical signals, a pattern in the detected vibration represented by that/those signal(s), and matching the identified pattern to one of one or more known patterns, wherein each known pattern corresponds to a respective road surface classification. The method further comprises classifying the road surface in accordance with the road surface classification corresponding to the known pattern matching the identified pattern. A system comprising one or more sensors carried by the vehicle that is/are configured to detect a vibration, and a pattern classification system for performing the methodology described above, is also provided.

    Abstract: A system and method of transmitting data within a vehicle over a vehicle bus includes: constructing at an electronic control unit (ECU) a serial bus message that includes a data message and a message authentication code (MAC) that is created using a secret key stored at the ECU, a MAC algorithm, and the data message; transmitting the serial bus message to a receiving ECU over the vehicle bus; and authenticating the serial bus message at the receiving ECU using a copy of the secret key stored at the receiving ECU by creating a copy of the MAC from the data message included in the serial bus message, the copy of the secret key, and the MAC algorithm; comparing the MAC included in the serial bus message with the copy of the MAC created at the receiving ECU; and rejecting or accepting the data message based on the comparison.

    Abstract: A server includes an import module that receives a first content file and a first instruction file from a design network. The first instruction file includes a first set of parameters. A job request module, based on the first instruction parameter set, determines a second parameter set and generates a second instruction file comprising the second parameter set. The job request module transmits the first content file and the second parameter set to a signature server. An export module receives a signature file from the signature server. The signature server generates the signature file based on the second instruction file. The export module integrates the signature into the first content file to generate a second content file and downloads the second content file to at least one of a service server, a manufacturing server, and a supplier network.

    Abstract: An apparatus has a communication bus, a first circuit, and a second circuit. The first circuit is operational to generate a package, calculate a check value of payload data in the package with a particular cyclic redundance check variant and an obfuscation type, store an encrypted check value in a footer of the package, store an encrypted obfuscation code in a header of the package, and transmit the package on the communication bus. The second circuit is operational to receive the package from the communication bus, decrypt the encrypted check value to determine the check value calculated by the first circuit, determine an obfuscation type from the encrypted obfuscation code, perform a payload verification of the payload data with the particular cyclic redundancy check variant with the obfuscation type applied and the check value, and signal that the payload data is valid in response to passage of the payload verification.
