    摘要： Methods and apparatus to limit access to a secure personal network are provided. The method includes receiving an Internet protocol (IP) packet of a device including a confirmation value associated with the SPN. The method compares the confirmation value to a predetermined confirmation value and allows access to the SPN when the confirmation value matches the predetermined confirmation value. The IP packet is dropped otherwise. The confirmation value and the predetermined confirmation value are generated by an algorithm including a pseudorandom number generator, a hash function and a one-time password.

    摘要： Methods and apparatus for handing off an end-point associated with a first device to a second device within a locally accessible network operating in an Internet protocol (IP) environment that supports multiple addresses for each device are provided. The first device is in a currently established session with a third device within the IP environment. End-point information associated with the end-point of the first device is locally transferred to the second device. A further end-point, compatible with the currently established session, is configured by the second device using the transferred end-point information. The second device broadcasts an announcement to the locally accessible network, including the router, that the second device is associated with the further end-point.

    摘要： A method for joining a network resource as a joining node to a peer-to-peer network includes establishing a node ID for the joining node to be joined to the peer-to-peer network, routing the join message to an assignment node that manages resources with resource IDs closest to the node ID of the joining node, determining whether or not the node ID established is identical to respective ones of the node IDs on the peer-to-peer network, and joining the joining node to the peer-to-peer network, when the node ID of the joining node is not identical to any one of the node IDs on the peer-to-peer network.

    摘要： A method for use in a mobile device to expedite hand-off of mobile devices between access points first detects movement of the mobile device among the coverage ranges of the access points. A mobile device that moves from one access point to another periodically transmits information on the data link level connection of its new access point on the channel used to access its prior access point. A first mobile device that is coupled to access points in a particular area maintains network level access information for access points with which it has communicated. When a new mobile device enters the area, the first device detects the new device and transmits the list to the new mobile device, enabling the new device to connect to an access point without transmitting a router solicitation message or receiving a router advertisement message.

    摘要： The trusted computer network is protected behind a gateway that includes a bastion host and screening router which blocks all URLs associated with the trusted network. The bastion host includes a remote client authentication mechanism and web proxy component that verifies and translates incoming URL requests from authenticated remote clients. Authentication is performed using one-time passwords that are stored on a portable storage device. The user configures the portable storage device by operating configuration software from the protected side of the gateway. The portable storage device also stores plug-in software to enable the client computer to properly retrieve the one-time password and exchange authentication messages with the bastion host. Further security is obtained by basing the one-time password on an encrypted version of the user's PIN. A symmetric key used to encrypt the PIN is stored in a protected area within the portable storage device.
