| 20090254754 | LIGHTWEIGHT GEOGRAPHIC TRAJECTORY AUTHENTICATION VIA ONE-TIME SIGNATURES - A system and method for a vehicle-to-vehicle communications system that provide active safety applications employing lightweight geographic authentication using one-time signatures. The system and method require each vehicle to construct a discretized representation of its trajectory, which captures its kinematical history to a tunable degree of accuracy and to a tunable extent in the past. This trajectory information is then signed using a one-time signature. Thus, with every periodic message, the sending vehicle transmits the usual application payload, a signed version of the trajectory as described, and the digital signature over all of the fields. | 10-08-2009 |
| 20110066859 | FLEXIBLE BROADCAST AUTHENTICATION IN RESOURCE-CONSTRAINED SYSTEMS: PROVIDING A TRADEOFF BETWEEN COMMUNICATION AND COMPUTATIONAL OVERHEADS - A method for authenticating a message that is transmitted wirelessly. The method includes providing a set of private key values that define a private key and performing a key pair generation process that provides a key pair including the private key and a public key, where performing the key pair generation process includes applying one or more hash functions to the private key values, where a succeeding hash function provides a hash of a previous hash function. The scheme uses a signature generation process that generates a message digest by applying a hash function on the message to be signed and then separates the message digest into two parts including signing bits and selection bits and using the private key to sign the message. A receiver verifies the authenticity of the received message using the public key and a signature verification algorithm. | 03-17-2011 |
| 20110238997 | EFFICIENT TECHNIQUE TO ACHIEVE NON-REPUDIATION AND RESILIENCE TO DoS ATTACKS IN WIRELESS NETWORKS - A computationally efficient message verification strategy that achieves non-repudiation and resilience to computational denial of service attacks in conjunction with a broadcast authentication protocol that authenticates messages using a combination of a digital signature and a TESLA MAC. When messages are received at a receiver, the verification strategy separates the messages into messages with the same sender identification. The strategy then determines whether the TESLA MAC authenticator is valid for each message and discards those messages that do not have a valid TESLA MAC. The strategy collects the messages that have a valid TESLA MAC for each sender identification and performs a batch verification process on the group of messages to determine if the messages in the group have a valid digital signature. This strategy verifies each message in the group of messages if the batch verification process shows that the group of messages has a valid digital signature. | 09-29-2011 |

The system may allow the user to issue control commands (e.g., “channel up”) from the media player to the broadcaster, causing the source device to execute the commands. The broadcaster and the media player may employ several techniques for buffering, transmitting, and viewing the content to improve the user's experience. | 04-22-2010 |
| 20110033168 | METHODS AND APPARATUS FOR FAST SEEKING WITHIN A MEDIA STREAM BUFFER - A method of seeking within a time shift buffer includes receiving a media stream from a remotely located media source over a network, and generating a time shift buffer associated with the media stream. The time shift buffer includes a number of frames with keyframes provided at a certain intervals. When a seek request associated with a desired time within the media stream is received, the system determines a nearest keyframe within the set of keyframes that is previous to and closest in time to the desired time, displays the nearest keyframe, then considers in turn each of the frames subsequent to the nearest keyframe until a desired frame corresponding to the desired time is reached displayed. The system cancels the previous examining step and determines a new nearest keyframe in the event a second seek request is received. | 02-10-2011 |
| 20110035669 | METHODS AND APPARATUS FOR SEEKING WITHIN A MEDIA STREAM USING SCENE DETECTION - A system uses generated scene transition frames to allow fast seeking within a media stream. A set of scene transition frames associated with the media stream are generated, then transmitted along with the media stream from a remotely located media source over a network. A subset of the scene transition frames are displayed, allowing a desired scene transition frame to be selected from a subset of the scene transition frames based on user input. The media source can then be displayed (e.g., played) starting from a frame corresponding to the desired scene transition frame. | 02-10-2011 |
