The decoder may be configured to receive a key associated with entitlement information, and transmit the entitlement information over a network. The encoder may be configured to receive content from content providers, and to encode the content to create IP-compatible content, with access restrictions based on entitlement. The network entitlement handler may be configured to receive a request for requested content from the decoder; receive the access-restricted content including (including the requested content) from the encoder; and transmit the requested content over the network to the decoder using IP, when the decoder is entitled to receive the requested content. | 2009-10-08 |
20090252330 | DISTRIBUTION OF STORAGE AREA NETWORK ENCRYPTION KEYS ACROSS DATA CENTERS - Efficient mechanisms are provided for transferring key objects associated with disk logical unit numbers and tape cartridges from one data center to another data center. A request is received to transfer a source data center key object from a source data center to a destination data center. The source data center key object corresponds to a data block, such as a disk logical unit number (LUN) or a tape cartridge, maintained in a storage area network (SAN) and includes a unique identifier, an encrypted key, and a wrapper unique identifier. The encrypted key is decrypted using a source data center key hierarchy. Key information is transmitted from the source data center to the destination data center. A destination data center key object is generated using a destination data center key hierarchy. | 2009-10-08 |
20090252331 | METHOD OF SECURING TYPED CONVERSATION USING ENCRYPTION KEYS IN A VIRTUAL WORLD - The present invention is directed to a method of securing typed conversations using encryption keys when interfacing in a public environment established in a Virtual World, in a Massively Multiplayer Online Role-Playing Game (MMORPG). | 2009-10-08 |
20090252332 | METHOD FOR GENERATING DOWNLINK FRAME, AND METHOD FOR SEARCHING CELL - The present invention relates to a method for generating a downlink frame includes: generating a first short sequence and a second short sequence indicating cell group information; generating a first scrambling sequence determined by a first synchronization signal; generating a second scrambling sequence determined by a first short sequence and a third scrambling sequence determined by a second short sequence; scrambling the first short sequence with the first scrambling sequence; scrambling the second short sequence with at least the second scrambling sequence; scrambling the second short sequence with the first scrambling sequence; scrambling the first short sequence with at least the third scrambling sequence; and mapping one second synchronization signal including the first short sequence scrambled with the first scrambling sequence and the second short sequence scrambled with at least the second scrambling sequence and another second synchronization signal including the second short sequence scrambled with the first scrambling sequence and the first short sequence scrambled with at least the third scrambling sequence in the frequency domain. | 2009-10-08 |
