Electronic data files are broadly characterized as “messages” and a social network is constructed by analyzing one or more messages exchanged between various entities. Additionally, messages from structured and/or unstructured data stores are correlated using one or more common/related data elements from two or more messages. Further, the social network and the concepts contained in the exchanged messages (i.e. semantic network) can be visualized using a series of multi-aspect viewing tools. Finally, in conjunction with the social network and the semantic network, a message network based on the chronological relationship of the messages (event network) can be constructed to analyze and visualize how the messages relate to each other in a time-based reference model. Once visualized, the relationship of the concepts contained in the messages as well as the relationship between the entities and the timing involved in the exchange of messages can be analyzed for desired information.

The invention includes a communication network for rotating media channels between resources of an emergency services network and a conforming emergency system (CES). A conforming emergency system and one of the resources of the emergency services network dynamically establish a first media channel between one another over a transport network. With the first media channel established, the conforming emergency system and the resource exchange messages over the first media channel to facilitate the CES in handling emergency events. Responsive to a triggering event, the CES and one of the resources (the same or another resource) dynamically establish a second media channel between one another over the transport network. With the second media channel established, the conforming emergency system and the resource exchange messages over the second media channel to facilitate the CES in handling emergency events. The first media channel may be torn down.

A method and system for device discovery in a wireless network is provided. The device discovery involves directionally transmitting a data unit from a transmitting station over a channel in different directions to emulate omni-directional transmission, receiving the data unit transmissions from different directions at a receiving station, determining the quality of the transmissions received from the different directions, and detecting location information for the transmitting station relative to the receiving station based on the highest quality transmission among the transmissions received from the different directions. Further, if a channel has sufficient bandwidth to satisfy direct link communication between two stations, then during a direct link set-up stage, the two stations conduct a probing message exchange using omni-direction transmission, and upon successful probing, obtain communication link status information and set proper communication configurations for the two stations based on the communication link status information.

A method and system to support secure booting and configuration. The mechanism employs an optical link comprising a quantum channel that is used to send data encoded as quantum bits (qubits) via respective photons. Qubits encoded using a first random basis at the client and are sent to the boot server, which processes the qubits using a second random basis to extract the encoded data. A public channel is used to send data indicative of the second random basis to the client. A symmetric quantum key is then derived a both the client and the boot server using a comparison of the random basis' and the original and extracted data. The scheme enables the presence of an eavesdropper to be detected on the quantum channel. A DHCP message exchange is employed to obtain a network address, and, optionally, be provided with a network address for one or more boot servers. A boot image request is made to the boot server by the client, and a subsequent boot image is downloaded via a secure channel facilitated by the symmetric quantum key.

The invention relates to an authentication method intended for a telecommunications network, especially for an IP network. From a terminal (TE1) in the network a first message (RR) containing an authenticator and a data unit is transmitted to the network, the data unit containing information relating to the manner in which the authenticator is formed. For carrying out authentication in the network, the data unit contained in the first message is used for determining a check value, which is compared with the said authenticator. To make it unnecessary for the terminal to perform any complicated and heavy exchange of messages when attaching to the network and for still obtaining the desired security characteristics for use, such an identification unit is used in the terminal which receives as input a challenge from which a response and a key can be determined essentially in the same manner as in the subscriber identity module of a known mobile communications system, a set of authentication blocks is generated into the network, of which each contains a challenge, a response, and a key, whereby the generation is performed in the same manner as in the said mobile communication system, at least some of the challenges contained by the authentication blocks are transmitted to the terminal, one of the challenges is chosen for use at the terminal, and, based on it, a response and key for use are determined with the aid of the terminal's identification unit, in the said first message (RR) the network is notified with the aid of the said data unit of which key corresponding to which challenge was chosen, and the authenticator of the first message and the said check value are determined with the aid of the chosen key.

By introducing a hierarchical encryption scheme and the use of asymmetric cryptography, the critical information in message exchanges is concealed from unauthorized entities. This helps greatly in preventing man-in-the-middle attacks faced by inter-working. In addition, access control is conducted by introducing a network structure having a rule interpreter that is capable of mapping general rules to WLAN specific commands. It obviates the needs for mobile user's home network to understand information about every WLAN it is inter-worked with. A common interface independent of WLAN technologies could be used by the home network for all the WLANs. The above conception provides a solution to the problems of the protection of user identification information and access control in the inter-working of WLAN.

A server has a firewall module that performs accounting of traffic seen at the server. The traffic includes message exchanges, such as HTTP requests and HTTP responses. The server tests the message exchanges to determine if they match any of several message exchange categories. The server keeps statistics on matching traffic, for example the rate of matching traffic generated by a particular requesting client. Typically, the server is a proxy server that is part of a content delivery network (CDN), and the message exchanges occur between a client requesting content, the proxy server, other servers in the CDN, and/or an origin server from which the proxy server retrieves requested content. Using the message exchange model and the statistics generated thereby, the server can flag particular traffic or clients, and take protective action (e.g., deny, alert). In an alternate embodiment, a central control system gathers statistics from multiple servers for analysis.

The present invention is a system and method for wireless emergency notification. In embodiments, a Civic Notification Service Centre (CNSC) generates a notification message, the notification message including a location identifier and notification information. The location identifier represents a geographical area such as a postal code, city street, neighborhood, or municipality. The CNSC transmits the notification message to a message switch that translates the location identifier to at least one device identifier such as a CAP code that is allocated to a set of notification devices assigned to the geographical location defined by the location identifier. Alternatively, the device identifier could be directly input within the notification message. After translation, the resulting notification message is transmitted to a set of base stations which subsequently transmit the notification message to a plurality of notification devices. The notification devices programmed with the device identifier within the notification message process the notification information. In some cases, a select set of base stations could be defined to transmit a notification message and therefore a limited wireless coverage area would be used that primarily focuses on the geographical area defined by the location identifier of the message. This notification system allows for the bypassing of the PSTN which ensures that in times of emergency, when the PSTN tends to be over-loaded, the notification message can still be delivered to the appropriate notification devices.
