A system is provided that uses identity-based encryption to support secure communications. Messages from a sender to a receiver may be encrypted using the receiver's identity and public parameters that have been generated by a private key generator associated with the receiver. The private key generator associated with the receiver generates a private key for the receiver. The encrypted message may be decrypted by the receiver using the receiver's private key. The system may have multiple private key generators, each with a separate set of public parameters. Directory services may be used to provide a sender that is associated with one private key generator with appropriate public parameters to use when encrypting messages for a receiver that is associated with a different private key generator. A certification authority may be used to sign directory entries for the directory service. A clearinghouse may be used to avoid duplicative directory entries.

A method for generating and maintaining a pruned broadcast tree for a network of switches operating multiple simultaneously active paths between devices with a load balancing family of protocols. The pruned broadcast tree is preferably generated as a by product of cost propagation aspects of the load balancing protocols exchanged among cooperating network switches. The load balance protocols operable within the network switches in association with the present invention permit multiple simultaneously active paths to be utilized among the network devices. The pruned broadcast tree is therefore used to reduce the latency of broadcast messages propagated within the network switches to reach all devices in the network. The broadcast tree defines a minimized set of devices to which a broadcast message need be forward to assure transmission to all network devices. The pruned broadcast tree, once established, is updated only in response to failure of a link and recovery of a failed link. A separate protocol of the present invention enables such pruned broadcast tree modifications and restoration.

A multiplayer handheld game employs individual game units having individual displays. Players can prepare their moves in secret on their game unit using controls and the individual displays, but when the game units are joined together, the game plays out on the aggregated screen. The game units employ digital signatures to ensure that all play is fair and that the virtual game pieces and characters in play have not been doctored or are otherwise fraudulent. Game results can be uploaded to a remote, secure server, which also serves as a backup for user data. Customization, improvements, and additions to the virtual game pieces and characters can be performed in conjunction with the secure server.

The invention provides methods and related systems for embedding and detecting watermarks in images, such as JPEG or MPEG formatted images as well as other types of image signals. One method receives transform coefficients of the image, and changes the value of selected coefficients to embed watermark data in the coefficients. The changing of the coefficients is controlled such that it both embeds the data and forms an orientation signal that facilitates determination of rotation or scale of the image. Another aspect of the invention is a variation of embedding a watermark in an image. This method receives message bits to be embedded in the image, receives transform coefficients of the image, and maps the message bits to selected transform coefficients. The method changes the value of selected coefficients to embed data in the coefficients. The characteristics of the image are used to control the change of transform coefficients to embed the watermark, and a bit rate control is used to modify the change of transform coefficients to embed the watermark according to a bit rate limit.

For an object-based application being executed in a digital computing system a framework is provided for managing information retrieved from a structured database, such as a relational database. The processor is used to construct a single cohesive data structure, called a relational cache, that comprises all the row instances and that represents information retrieval from the structured database in a form suitable for use by one or more applications. An application may have several of these relational caches active at any one time, some of which may represent separate user editing sessions, where each session may be saved or discarded independently. The framework ensures that only one copy of a row instance is in a given cache at any given time, even if several different queries return the same information from the database. Row instances within the relational cache may be modified by the application, where the row instances are marked as modified but not saved to the database at that time. The framework ensures all modified row instances within the cache are saved at one time, which are presented to the database as a single transaction, with individual rows ordered so as not to violate database referential integrity rules. Other properties of the framework are disclosed.

The use of a different freshness parameter for each security base key derivation avoids key stream repetition. Further, a user plane encryption key is derived based on the generated unique non-repetitive security base key associated with the second eNB for encrypting data transfer over at least one data radio bearer.

The present invention relates to multi-application, secure operating systems for small, secure devices, such as smart card microcontrollers. In particular, the present invention relates to mechanisms for secure runtime upload of applications onto small devices, authorisation mechanisms and the ability for authorised execution of multiple applications on the devices, where an application may be potentially larger than the microcontroller memory size. The mechanism simplifies life-cycle smart card management aspects related to post-issuance application (“applet”) upload and upgrade. Mechanisms to prepare applications (i.e. compiler techniques) using a common set of project files in one compiler toolset, for execution in a dual host & chip processor environment are described. These help automising the programming of the communication interfaces between the host and chip applications. An important motivation for the present invention is to provide a secure co-processor environment for general computer applications in order to counter software piracy, and to allow new models for secure electronic software distribution and software licensing.

A method and apparatus for transferring data between a handheld device and a network over a wireless communications link. A datapool manager breaks files into virtual blocks and adds the virtual blocks to a datapool. A communications manager converts the virtual blocks into transportation packets and controls the transfer of the transportation packets between the handheld device and the network. After a transportation packet is transferred, an acknowledgment is returned indicating that the transfer was successful. If the transfer of a file is interrupted, then, upon reestablishing the wireless link, only those transportation packets for which an acknowledgment has not been returned are transferred. To properly reconstruct the file, a pointer indicates the location of each transportation packet in the file. Furthermore, to enable the use of a partially transferred file, a table of information is maintained indicating the validity of the partially transferred file. Transportation packets are identified as instruction packets or data packets. When determining the order of transfer, priority is placed on the transfer of instruction packets.

A global information management system (GIMS) includes a collection of standards and methods that allow information management on a global scale. A GIMS computer network includes a central registration database (CRD) and one or more GIMS computer systems connected over a network. Each GIMS computer system includes a relational database having a set of standardized tables. The CRD may provide a GIMS network-unique system ID to each GIMS computer system. Each GIMS computer system uses the GIMS network-unique system ID as part of a primary key for each record generated by and stored in the set of standardized tables of the GIMS database. The GIMS enables global database normalization through the globally unique identification of database records.
