    摘要: The invention provides a secure Wi-Fi communications method and system. In an embodiment of the invention, unique physical keys, or tokens, are installed at an access point and each client device of the network. Each key comprises a unique serial number and a common network send cryptographic key and a common network receive cryptographic key used only during the authentication phase by all components on the LAN. Each client key further includes a secret cryptographic key unique to each client device. During authentication, two random numbers are generated per communications session and are known by both sides of the wireless channel. Only the random numbers are sent across the wireless channel and in each case these numbers are encrypted. A transposed cryptographic key is derived from the unique secret cryptographic key using the random numbers generated during authentication. Thus, both sides of the wireless channel know the transposed cryptographic key without it ever being transmitted between the two.

    摘要: The invention provides an external in-line device (“Subnet Box”) placed between a network and an access point to achieve secure Wi-Fi communications without needing to modify the access point. The Subnet Box comprises an embedded token and will authenticate users based on pre-stored access rights. In at least one embodiment of the invention, the Subnet Box comprises: a first communications port for intercepting data packets communicated to and from a wired communications network; a second communications port for intercepting data packets communicated to and from a wireless access point, wherein the wireless access point is an edge device of the wired communications network; a database comprising a number of serial numbers each associated with a client token and a secret cryptographic key; and a processor for determining whether a computing device having a client token can access the wired communications network via the wireless access point. The processor establishes a secure tunnel between the computing device and the first communications port.

    摘要: A method of per-packet keying for encrypting and decrypting data transferred between two or more parties, each party having knowledge of a shared key that allows a per-packet key to differ for each packet is provided. Avoiding the use of a static session key during encryption offers several advantages over existing encryption methods. For example, rejecting packets received with duplicate sequence numbers, or sequence numbers that are beyond a specified deviation range mitigates Replay Attacks.

    摘要: The invention provides a method and system for locally tracking network usage and enforcing usage plans at a client device. In an embodiment of the invention, a unique physical key, or token, is installed at a client device of one or more networks. The key comprises a usage application and one or more access parameters designated the conditions and/or limits of a particular network usage plan. Upon initial connection to the network, the usage application grants or denies access to the network based on an analysis of the current values of the access parameters. Therefore, network usage tracking and enforcement is made simple and automatic without requiring any back-end servers on the network while still providing ultimate flexibility in changing billing plans for any number of users at any time.

    摘要: A system, method, and apparatus for automatically and dynamically updating options, features, and/or services available to a client device operating in a client-server environment. The client device includes a client template database for storing templates defining a configuration of the client device. This configuration determines the options, features, and/or services available to a client device and the user of the client device. A server includes a server template database for storing the most current or latest versions of the templates used to configure the client device. When a user enters a user request at the client device, the client device transmits an associated information request to the server. The information request includes a client template identifier associated with the information request and a client template version identifier. The server receives the information request and compares the client template version identifier to a version identifier for a corresponding template in the server template database, to determine if the client device has the latest version of the template. If it does not, then the server transmits an information response message to the client, including a template update.

    摘要: A pager based information system is used to transmit both conventional private messages (using unique pager IDs) and two types of unconventional multi-recipient (M-R) messages (using database IDs and group IDs), all using the conventional POCSAG pager transmission format. Operation of the pager is software controlled through the use of a microprocessor and a RAM; auxiliary chips are not needed because of the relatively slow transmission speeds. Authority to receive the M-R messages is provided at the time of manufacture (database IDs) or via broadcasts (group IDs). Database type M-R messages are stored in the pager RAM in a hierarchial or tree structure. The software controlled pagers permit the over-the-air modification of the operation of selected pagers, such as the addition or deletion of group IDs and the change in the tree structure of the storage area for the database messages. The pager includes a real time pager clock which is update by pairs of broadcast time messages, the second having a time correction for the first.
