Abstract: A content owner registers with an identity authority by providing information about the content owner and a public key of a public/private key pair. The content owner registers content to the identity authority and signs the multiple segments of the content with the private key of the public/private key pair. A system that receives the signed content determines an indicated content owner of the received media content and communicates with the identity authority to confirm that the media content was produced by the indicated content owner. The receiving system requests the public key of the content owner from the identity authority and uses the public key to verify the signature of each media content segment. Accordingly, the receiving system is able to determine if the media content was manipulated after being distributed by the content owner.

Abstract: Aspects of the present disclosure address systems, methods, and devices for enabling secure communication between electronic control units (ECUs) in a vehicle. The system may include a first and second ECU from a plurality of ECUs in the vehicle. The first ECU is to enable secure communication between the plurality of ECUs by performing operations that include provisioning the second ECU with authentication data for authenticating messages exchanged with a third ECU and provisioning the third ECU with a set of security keys to enable the third ECU to securely exchange messages with the second ECU. The second ECU receives, from the third ECU, a secure message that is cryptographically signed using a security key from the set of security keys provisioned to the third ECU, and the second ECU authenticates the secure message by comparing the authentication data with an authentication signal.

Abstract: A method for notifying a user about a broadcast event comprises the steps of receiving at a management center at least one user keyword; receiving at the management center an identifier of at least one user unit, said at least one user unit being linked to the user; in the management center, determining a set of broadcast data linked to broadcast events; forming a query containing data identifying at least a subset of the set of broadcast data and at least one user keyword; sending said query to a plurality of data sources; receiving at the management center a response to the query, the response indentifying at least one event; transmitting a notification containing an identifier of the at least one present or future event in said response and the identifier of the user unit so that the user unit may notify the user of the events in the response.
