摘要:
A method for providing a secure communications link between a home PC and a vehicle through a wireless access point. The method includes providing a wireless connection between a vehicle communications system and the wireless access point and causing a user of the PC to initiate a communication with the vehicle communications system through the wireless access point so as to allow the user to send information to the vehicle from the home PC. The method also includes causing the vehicle communications system to send an authentication challenge to the PC, such as identifying a user name and password, to authorize the user to communicate with the vehicle communications system, and establishing a secure communications link between the vehicle communications system and the PC if the user responds to the challenge with a correct response.

A mobile client system initiates a wireless communication with a transaction system and receives a digital certificate from the transaction system in response. The digital certificate includes an embedded geographic location of the transaction system. The mobile client system also compares the geographic location of the transaction system with a current geographic location of the mobile client system and establishes an encrypted communication channel with the transaction system upon determining that the location of the transaction system is in proximity of the current location of the mobile client system. The mobile client system further sends the user credentials to the transaction system via the encrypted communication channel. Upon successful authentication of the mobile client system via the user credentials, the mobile client system performs a transaction with the transaction system using a graphical user interface of the client system.

A system and method for securely flashing a controller, where the controller includes at least one main processor and at least one secondary processor, and where the processing duties are distributed between the processors. A programming tool provides a content file to be flashed and a digital signature to the controller. The controller calculates a hash value of the content file, decrypts the digital signature using a public key to generate a decrypted hash value, compares the decrypted hash value to the calculated hash value, and determines that the content file is valid if the decrypted hash code matches the calculated hash value, where one or more of the steps of calculating the hash value, decrypting the digital signature, comparing the decrypted hash value to the calculated hash value and determining that the content file is valid, is performed by the main processor for the secondary processor.

A communication system of a vehicle includes a mode determination module and a connection control module. The mode determination module sets a mode of operation to one of a first mode and a second mode based on a comparison of a common name (CN) of a root certificate with first and second predetermined CNs associated with operation in the first and second modes, respectively. The connection control module selectively transmits a request to one of a first server and a second server to establish a secure wireless connection between the connection control module and the one of the first and second servers. The first and second servers are different, and the first and second predetermined CNs are different.
摘要:
A system and method for enhancing vehicle diagnostic and prognostic algorithms and improving vehicle maintenance practices. The method includes collecting data from vehicle components, sub-systems and systems, and storing the collected data in a database. The collected and stored data can be from multiple sources for similar vehicles or similar components and can include various types of trouble codes and labor codes as well as other information, such as operational data and physics of failure data, which are fused together. The method generates classes for different vehicle components, sub-systems and systems, and builds feature extractors for each class using data mining techniques of the data stored in the database. The method also generates classifiers that classify the features for each class. The feature extractors and feature classifiers are used to determine when a fault condition has occurred for a vehicle component, sub-system or system.
摘要:
A system and method for authenticating the source and ensuring the integrity of traffic data collected from probe vehicles while maintaining the privacy of the data's source. This is accomplished by dividing the traffic analysis functionality into two distinct responsibilities: data collection, including authentication and verification, and data processing, and assigning each responsibility to a different entity, such the first entity has access to authentication information which identifies the data's source but not to traffic information such as the source's location, and the second entity has access to the traffic information but not to the authentication information which identifies the data's source.

A method and system are provided for secure over-the-air modification of vehicular options by a vehicle user. The system includes a vehicle and a secure server. The vehicle includes receiver circuitry for receiving and demodulating wireless signals and a controller coupled to the receiver. The secure server is accessible by the vehicle user and generates a vehicular option modification package for provision to the vehicle by generating option parameter modification instructions in response to user parameter modification requests from the vehicle owner and generating authentication information in response to unique server authentication information associated with the secure server. The vehicle's receiver demodulates received wireless signals to generate the vehicular option modification package and the vehicle's controller authenticates the vehicular option modification package and, when the vehicular option modification package is authenticated, modifies the vehicular options of the vehicle in response to the parameter modification instructions.

Methods and apparatus are provided for enabling communication between an information handling device, such as a computer, and a vehicle. A dongle is provided for enabling the communication and includes an external coupling device, dongle transceiver circuitry, and a dongle controller. The dongle transceiver circuitry enables remote keyless entry communication between the dongle and the vehicle. The external coupling device couples the dongle to the information handling device, and the dongle controller is coupled to the external coupling device for determining when the dongle is coupled to the information handling device. The dongle controller is also coupled to the dongle transceiver circuitry for providing a remote keyless entry wakeup message to the dongle transceiver circuitry in response to receiving a communication initiation signal from the information handling device.
摘要:
A system and method for providing secure one-way transmissions in a vehicle wireless communications system. The system and method rely on a clock signal to assure that the vehicle and server receive proper messages. The vehicle and the server will periodically synchronize their internal clocks to a global clock signal. The server will add its local time to the body of a message including a vehicle identification number and a function code. The server will then encrypt the message and transmit it to the vehicle. The vehicle will decrypt the message and compare the transmitted vehicle identification number with its identification number. If the identification numbers match, the vehicle will then see if the time in the message is within a predefined window of the vehicle time. If the transmitted time is within the predefined window of the vehicle time, the vehicle will accept the message and perform the function.
