Abstract: In a vehicle-to-vehicle wireless communication system utilizing certificates to verify trustworthiness of received communications, a method for distributing a list of certificate revocations to vehicles in the communication system. At least one main station transmits a list of certificate revocations to at least one vehicle and the vehicle thereafter transmits the list of certificate revocations to other vehicles in the communication network. Each of the other vehicles in the communication network updates its list of certificate revocations in response to the receipt of the list of certificate revocations from another vehicle in the system. The other vehicles thereafter transmit their updated list of certificate revocations to other vehicles in the system.

Abstract: A system provides a multi-sided media viewer capable of displaying media assets from an electronic archival news and content database. Each side of the media player contains different information regarding the media asset. A primary side of the media asset may display a media asset related to an educational program, such as a course curriculum or the like. The secondary sides of the media viewer may contain additional information regarding that media asset, including personalized information generated by a system user as well as automatically populated information, such as information collected from other external news services or content providers. The system may further provide an educational game in which users are encouraged to find and draw connections between media assets to create an interconnection of related news items.

Abstract: In a vehicle-to-vehicle communication network utilizing PKI security methods to protect communications and in which the PKI encryption utilizes a Certificate Authority having both a private key and a publicly distributed key, a method for allocating multiple certificates for each vehicle which are assigned to each vehicle in the communication network. The method includes the step of assigning a unique secret key k to each vehicle in the communication network. The Certificate Authority then creates a plurality of public key and private key encryption pairs for each vehicle and each encryption pair is associated with an index i. A plurality of certificates are then created with one certificate for each value of the index. A revocation list comprising the secret keys is maintained by the Certificate Authority so that all encryption pairs assigned to a particular vehicle may be revoked by the secret key k corresponding to that vehicle.
