Patent number: 10887091Abstract: Techniques are disclosed for multi-hop security amplification. The techniques disclosed provide multi-hop security amplification by applying a secret sharing scheme to data as the data is routed within a network to an intended recipient device. In an embodiment, a sending device divides the data into shares based on a secret sharing scheme, and sends the shares to respective network nodes in a network. These network nodes then divide their respective shares into lower-level shares based on the secret sharing scheme, and route the lower-level shares to downstream network nodes for further routing to the intended recipient device. The intended recipient device receives some or all of the lower-level shares and reconstructs the data from the received lower-level shares. In an embodiment, the secret sharing scheme is a threshold-based secret sharing scheme, such as Shamir's secret sharing scheme.Type: GrantFiled: November 27, 2018Date of Patent: January 5, 2021Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Benjamin Kapp, Jibu Abraham

Patent number: 10884095Abstract: Techniques are provided for geolocation of a radar emitting source. A methodology implementing the techniques according to an embodiment includes calculating time difference of arrival (TDOAs) of ground emitter radar pulses, within a dwell period, between two long baseline interferometer (LBI) antennas. The TDOA calculations are based on a precision estimate of the time of arrival of the radar pulses. The method further includes calculating an LBI phase wrap disambiguation factor based on (1) the TDOAs, (2) an average of frequencies of the radar pulses within the dwell period, and (3) an average of phase shifts of the radar pulses between the LBI antennas within the dwell period. The method further includes mapping a curve of points onto the surface of the earth based on an LBI cone angle calculation employing the LBI phase wrap disambiguation factor. The curve of points is associated with a geolocation of the ground emitter.Type: GrantFiled: March 13, 2019Date of Patent: January 5, 2021Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Richard Schiffmiller, Lawrence Sheldon

Patent number: 10887334Abstract: A cybersecurity system and method utilizing SOUND reputation, where a set of reputations are associated with each actor on a network. The actors on a network may be users, hosts, applications, and the like. The associated reputations are aggregated and updated as new information about an actor's activity is reported according to a defined and modifiable protocol, or policy. The actor's activity may be reported by one or more threat sensors. The effect of a particular misbehavior can be tuned to match the needs of the specific network. When a bad actor's reputation sinks too low, the system can take whatever action is appropriate: reports can be sent, an operator can be notified, the offender can be cut off from the network, or the like.Type: GrantFiled: September 6, 2018Date of Patent: January 5, 2021Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Peter D.
