Method and system for securely exchanging encryption key determination information
A system and method for securely exchanging plurality of information items used to generate a plurality of encryption keys used in a public key-and-private key system. In accordance with the principles of the invention, elements of exchanged information items, such as public key and synchronizing indictors are encrypted before the exchange. The information item element is encrypted using an encryption key determined from information items that were previously exchanged. The encryption of information items used to determine subsequent encryption keys provides additional security to the encryption key used in the transmission of informational data as the encrypted elements of the information item must be decrypted before the data message encryption key can be decrypted. The process of exchanging encrypted information items can be repeated until an agreed upon number of encrypting keys is determined. |

Encryption of security-sensitive data by re-using a connection
Techniques are provided for processing data. Connections having different security properties are stored, wherein each of the connections allows applications at the client computer to access data sources at a server computer. A request is received from an application to access a data source, wherein the request has associated security properties. In response to the client computer requesting establishment of a connection on behalf of the application, it is determined whether there is a stored connection that used a same set of security properties as are associated with the request from the application and that connected to the data source that the application requests access to. In response to determining that there is a stored connection that used the same set of security properties and that connected to the data source, the connection and an associated client encryption seed, client encryption token, server encryption seed, and server encryption token are re-used. In response to determining that there is not a connection that used the same set of security properties and that connected to the data source, a new client connection key, client encryption seed, client encryption token, sever connection key, server encryption seed, and server encryption token are generated. |

Method for the provision of a network service
Methods and systems provide for sharing information between computer networks in which the information to be shared is required at one location (e.g. for the provision of a data-processing service) but is only available at a separate location. The information may be deliberately absent (e.g. for privacy reasons) or may be unavailable as an artifact of the computer network(s) involved. For the provision of a data-processing service, where several different devices on one network may service contiguous requests from a client device on another network according to a load-balancing strategy, data is propagated once only through the service network. Network communication software is subsequently amended to provide the minimal information necessary for a device on the service network to retrieve the information pertinent to the client device and necessary for its service. Therefore, a web-based single sign-on scheme can operate over HTTP to authorize data-processing services, such as web-filtering services. |

System and method for achieving highly scalable real-time collaboration applications using HTTP
A highly scalable and highly responsive RTC system uses asynchronous or non-blocking I/O and HTTP response queuing to avoid server overload. The system distinguishes between two types of requests: an update request and a change request. An update request is a request used to fetch an update or change notification. A change request is a request to change some data related to the real-time session. For a given RTC session, the server first checks whether any updates exist for an update request. If an update exists, the server code can send an immediate response to the client. However, if no update exists, the server code application sets a well-defined HTTP response header, and then responds. Once the server code application responds, all application server resources are freed, and the application server is free to handle the next requests without blocking any thread. |

The alarm signal is also propagated to upper level control systems for generating appropriate responses in other zones. To provide the different zones and avoid interference, the transmit power of the sensors and actuators is controlled as a function of two or more other devices. |

Multiple beam antenna base station
Systems, devices and method are provided in association with a multiple beam antenna base station. One system embodiment includes a multiple beam antenna base station configured to communicate data to a number of subscriber stations using a number of multiple antenna beams. The multiple beam antenna base station is implemented with an independent receiver for each of the number of multiple antenna beams. In various embodiments, each of the independent receivers of the multiple beam antenna base station is configured to determine signal quality of a preamble of an uplink transmission from a subscriber station via the number of multiple antenna beams. |

Method and system for datalink ground station selection
A method for selecting a ground station for communication with an aerial vehicle is provided. The method comprises receiving at an aerial vehicle one or more messages from one or more ground stations. The method includes storing one or more signal strength values corresponding to the one or more received messages in a data structure for each respective one or more ground stations received during a predefined time period. The data structures for each of the one or more ground stations is updated. The average of the signal strength values stored in each data structure is calculated. The method compares the average signal strength of each of the one or more ground stations and selects which ground station the aerial vehicle is to communicate with based on predefined criteria. |

Method for handover between heterogenous radio access networks
A method for handover between heterogeneous radio access networks is disclosed. When a multi-mode mobile station performs Inter-RAT handover, pre-authentication is performed before implementing a link layer handover procedure with a target access point. The pre-authentication method has as little an effect on currently served quality of service as possible and the handover is efficiently performed using the pre-authentication method. The pre-authentication is performed through medium independent handover (MIH) and various MIH primitives for pre-authentication are provided. |

Apparatus and method for splicing multimedia session on communication networks
The present invention relates to an apparatus and method for splicing multimedia session on communication networks. The apparatus comprises a handoff manager, a session migration manager and a session splicing module. The handoff manager monitors whether a mobile host is roaming to other subnets or not, and acquires a new IP address and issues a control signal when a handoff event is triggered. When a user triggers a migration action, the session migration manager, based on the monitoring status of an ongoing session, sends a state message to a target host for performing session migration, enables a media player, and issues another control signal. The session splicing module respectively receives the two control signals, and performs a corresponding session splicing for each control signal to persist session connection. |
