International Classification:

H04L 29/06
H04K 1/00

US Classification:

713158, 713156, 380270

Abstract:

A computer-implemented method for generating a hierarchical set of certifiers nodes for a public key infrastructure within an ad-hoc network. The method includes determining at least one potential certifier node that is eligible to become certifier nodes from a set of nodes in an ad-hoc network, creating a new certifier node from the at least one potential certifier node based on a selection criteria, and creating a parent-child relationship with the new certifier node.

International Classification:

H04L 9/00

US Classification:

713158

Abstract:

A computer-implemented system for implementing maintenance and distribution of revocation information within an ad-hoc network. The system includes at least one network node. The network node includes a computer implemented application configured to maintain revocation information in computer memory and distribute the revocation information to other network nodes using a two stage distribution method. The distribution method includes a first stage wherein the revocation message is transmitted to all certifier nodes within the ad-hoc network, and a second stage wherein each certifier node distributes the revocation message to at least one non-certifier node associated with the certifier node.

International Classification:

H04L 1/00
H04L 12/28

US Classification:

370254, 370252

Abstract:

The present invention provides a method for using an Organization and Control Proxy (OCP) to configure a network communications infrastructure. OCP functionality is distributed across nodes possessing OCP elements. Intercommunication between the OCP elements is implemented via a unifying mesh waveform for network discovery, propagation of network and radio-frequency (RF) socket usage information, and management and control of instances of dynamic socket waveforms. An extensible language for specification of waveform properties is used by the OCP elements to negotiate spectral use information and to negotiate configurations between two or more endpoints of a dynamic socket waveform connection. A network stack is configured by the OCP to provide requested service to an end user.

International Classification:

H04B 1/00

US Classification:

375132

Abstract:

A spread spectrum communication system includes a transceiver configured to transmit a spread spectrum waveform. The spread spectrum waveform comprises transmitted signals at varying frequencies within a radio frequency spectrum of operation. The frequency variation is controlled according to a hopping sequence. A spectral sensor of the communication system is configured to dynamically scan the radio frequency spectrum of operation and to generate channel occupancy data based upon the scans. A real time hopping sequence generator is configured to dynamically generate the hopping sequence in real time as a function of the channel occupancy data.

International Classification:

H04B 7/212

US Classification:

370322, 370324

Abstract:

A method is provided to control scheduling of transmission and reception by a TDMA radio. This method allows individual transmissions and receptions to be independently configured for different frequencies, coding rates, modulation schemes, in fact anything which the radio modem allows to be configured. In addition, this scheduling and configuration may be configured and reconfigured in real time without disrupting radio operations.

US Classification:

713188, 726 24, 726 26, 713182, 713189

Abstract:

A system for preventing computer malware from exfiltrating data from a user computer in a network via the internet. A host-based network process monitor intercepts network traffic information from the user computer and transmits a network request including user and application information including the network traffic information. An authorization server cooperates with the host-based network process monitor for i) verifying whether the user and process in the network request should have network access, and ii) cryptographically signing the intercepted network traffic information with an authorization server key, to authorize network access for the intercepted network traffic information. A firewall system is operably connected to the user computer and the authorization server configured to inspect the network traffic information from the user computer and reject any traffic information not signed with the authorization server key.

Abstract:

A system capable of operation with dynamic sockets includes a plurality of communications devices. Each of the plurality of communications devices includes high band channel radio resources capable of communications at 900-2800 MHz and socket radio resources capable of communications at 30-1000 MHz. The high band channel radio resources and the socket radio resources are significantly separated in frequency so that the high band channel radio resources and the socket radio resources are suitable for concurrent operation with no interference and minimal isolation, co-site problems to solve in each of the plurality of communications devices. The plurality of communications devices are connected to a unifying mesh network by the high band channel radio resources. The unifying mesh network is suitable for allowing the plurality of communications devices to communicate with one another. When data needs to be transferred among a group of communications devices, a dynamic socket connection is negotiated on the unifying mesh network and is then formed with the socket radio resources.
