Abstract:
A method and a system of managing a policy managed system that includes a policy managed element. The method restricts the policy managed element so that internal configurations and actions of the policy managed element do not violate any policy rules generated external to the policy managed element. The method also prevents the policy managed element from generating policy that exit the policy managed element. The method, at a policy executive element (PEE) located remote from the policy managed element, restricts internal configurations and actions of the PEE so that the PEE does not violate any policy rules generated external to the PEE. The PEE includes a policy generation point (PGP) that the method allows to generate new policy rules that do not violate any existing policy and provides the new policy rules to the policy managed element.
Abstract:
The current disclosure is directed to broadcasting information among nodes in the network. More specifically, the current disclosure relates to directional networking among nodes in the network. The directional broadcasting system allows for a more efficient way to deliver broadcasting information among nodes where at least some of the nodes use directional antennas.
Abstract:
A spectrum sharing system includes an advanced beacon (e.g. a low latency RF link) as part of an information sharing subsystem. The advanced beacon signal carries radar spectrum transmission schedule in an obfuscated way such as not to reveal the geolocation of the radar. The information sharing subsystem directs nodes, such as cell phones, to share spectrum based on spectrum sharing instructions contained in the advanced beacon. The spectrum sharing system permits out-of-band sharing of spectrum white space, as well as sharing of in-band spectrum gray space.
Abstract:
An asynchronous medium access control layer scheduler increases efficiency for directional mesh networks by removing extra overhead in the time slots. The efficiency is increased by dividing time slots into sub-slots to allow for a receiving node to be offset by at least one sub-slot from the transmitting node. This enables the scheduler to more efficiently schedule operations for the nodes so that nodes can be performing other functions rather than waiting to receive a transmission or waiting after transmitting a transmission. The sub-slots may be sized to approximate the transmission propagation time or time of flight delay.
Abstract:
A system and method of cognitive radio control to allow for low probability of detection and/or low probability of exploitation communications in a contested or hostile environment. The cognitive radio system of the present disclosure can reason over policy constraints and real-time data to make dynamic changes to mission parameters in real-time.

Abstract:
A system and method for repurposing of cryptographic capabilities in an electronic warfare (EW) environment is presented. A method begins by determining in a client system a cryptographic function to be performed; however, the client system does not have any cryptographic functionality. The client system then requests the cryptographic function be performed in a cryptographic logic that is physically secured with the client system and is external to the client system. The cryptographic logic performs the cryptographic function to produce a cryptographic result. The cryptographic result is then provided to the client system.
Abstract:
A system and method for controlling a radio transmitter from the application layer is presented. The method includes monitoring an uplink state of a shared channel at a cell manager and processing the uplink state, at least in part, in the application layer in the cell manager to produce processed uplink state. The processed uplink state is then broadcast in a control packet on a downlink of the shared channel to a subscriber manager. The processed uplink state is then further processed, at least in part, at the application layer in the subscriber manager to produce transmitter control data. The transmitter control data is then used control the radio transmitter.
