| 20100235641 | SECURITY TECHNIQUES FOR COOPERATIVE FILE DISTRIBUTION - Security techniques are provided for cooperative file distribution. An encryption key or a nonce (or both) are generated for a package containing one or more files that are to be sent in a cooperative file distribution system. Random access encryption techniques can be employed to encrypt a package containing one or more files to be sent in a cooperative file distribution system. One or more storage proxies are allocated to a package to be transmitted in a cooperative file distribution system, based on load. Access to trackers in the cooperative file distribution system is controlled using security tokens. Content can automatically expire using a defined expiration period when the content is uploaded into the system. Variable announce intervals allow the tracker to control how often the tracker will receive a message, such as an announcement or a heartbeat message, from peers in the system. | 09-16-2010 |
