Abstract:
A system and method are provided for establishing a network communication session using fast authentication. In a network system a client or user device may establish a communication session with a server using full authentication. If the session is interrupted or discontinued and resumption of the session is requested, a session identifier of the previously established session may be compared to the session identifier of the requested session. If a match is detected, the session may be resumed using a fast authentication (or re-authentication) procedure such that the session is resumed more efficiently and expediently. Fast authentication may be performed, for example, even when the first session and the resumed second session are of different authentication layers, different types of network interfaces and/or different locations. Thus, a session, such as a TLS session, may resume functionality among multiple defined authentication protocols or technologies such as 802.1X, PANA or cellular based systems.
Abstract:
The present invention provides improved quality of service through data transmission rate control in a network. Data rate control may be in the downlink or uplink direction and may be statically or dynamically configured. Rate control may be implemented at varying points in the network including but not limited to at the wireless host, at the access point, at a separate device such as a server or at a separate location within the network. In one example of the present invention, a rate enforcement function is provided for identifying data packets to be enforced or identifying mapping between each packet and corresponding access point. Also, a rate decision function is also provided for determining the data rate to be enforced for each of the access points or each of the wireless hosts.

Abstract:
Network architecture configured for open communication between a plurality of sub-networks. Each of the plurality of sub-networks has a different routable network addressing scheme. The architecture includes at least one broker node adapted to communicate using at least two different routable network addressing schemes. The broker node comprises an identification management module configured to collect peer-application addresses for nodes currently accessing a specific application, the peer-application addresses being associated with a specific application, an address resolution module configured to map each of the peer-application addresses to a sub-network specific routable network address and a network coordination module configured to monitor and coordinate sub-network communication capabilities between the broker node and at least one other broker node and elect a primary broker node for each sub-network which the broker node and at least one other broker node is capable of communication.
Abstract:
A system and method for automated determination of quasi-identifiers for sensitive data fields in a dataset are provided. In one aspect, the system and method identifies quasi-identifier fields in the dataset based upon a static analysis of program statements in a computer program having access to - sensitive data fields in the dataset. In another aspect, the system and method identifies quasi-identifier fields based upon a dynamic analysis of program statements in a computer program having access to -sensitive data fields in the dataset. Once such quasi-identifiers have been identified, the data stored in such fields may be anonymized using techniques such as k-anonymity. As a result, the data in the anonymized quasi-identifiers fields cannot be used to infer a value stored in a sensitive data field in the dataset.
Abstract:
Mobile wireless devices may receive data streams from multiple remote sensors. The sensors may have limited power supplies and memory capacity. Aspects of the invention use statistical characteristics of the sensor data streams and the cost of acquiring a single element of each stream to determine what sequence the sensors should send their data streams in. The cost of acquiring the data may be modified dynamically, depending on parameters such as block size. Additional factors, such as a sensor's buffer capacity, may limit the amount of stream elements that may be cached and affect the sensors' stream transmit sequence. The evaluation order may be dynamically modified using an event processing engine, to reflect both changing statistics of underlying sensor stream tuples and time-varying acquisition costs associated with individual streams. This helps to increase in the operational lifetime of the sensors and associated monitoring applications.
Abstract:
Methods for coordinating power usage and link adaptation in wireless communications are described. Terminals and/or access points (APs) may attempt to modify terminals' transmit power in relation to a desired communication data transfer rate. Link adoption may also be used in conjunction with the described methods.
