  • Patent number: 10171424
    Abstract: The presently disclosed privacy enhancing networks (PENs) comprises a network of gateways in communication with one or more controllers. By dynamically creating and tearing down unique data flow paths through a network of gateways for each individual data flow, the privacy enhancing network makes it more difficult for an adversary to glean information about communicating parties. Since each flow in a single data session may be routed through a different path, adversaries may find it more difficult to determine which data flows are associated with each data session. This in turn, makes it more difficult for adversaries to gather enough data traffic to break any encryption applied to the data flows. Furthermore, since each flow in a single data session can be directed along a different path, a privacy enhancing network may make it difficult for adversaries to even determine that the communicating parties are communicating at all.

  • Patent number: 10142159
    Abstract: Systems and methods are described for IP Address allocation. A computerized method includes receiving at a wireless access gateway a request from a subscriber to connect to a network, allocating a first IP address to the subscriber from a first pool of IP addresses at the wireless access gateway, and assigning a second IP address to the subscriber from a second pool of IP addresses at the wireless access gateway when the subscriber requests a network service.

  • Publication number: 20180069901
    Abstract: Systems and methods are described for providing cloud-based virtual local networks. A computerized method for providing cloud-based virtual local networks includes receiving at a network gateway a request for a network address from a network switch, communicating with a user device management entity (uDME) server to authorize the network switch, receiving an authorization response from the uDME server for the network switch, receiving a network address pool at the network gateway from the uDME server, and creating at the network gateway a virtual home router containing a virtual home router context that is unique to the virtual home router and associated with the network address pool.

  • Publication number: 20140344449
    Abstract: Computerized systems and computerized methods are provided for internet protocol (IP) address allocation for Wi-Fi clients in a manner that avoids assigning a public IP address to a device if the device is not first activated to use services provided by the network. A private IP network address is allocated to a device, wherein the private IP network address is only valid for a predetermined period, and only allows the device to activate itself with the network instead of providing the device full access to the network. The device is monitored during the predetermined period so that if the device is activated to use the network during the predetermined period, the computing device assigns a public IP address to the device so that the device can access a full set of services provided by the network.
