Abstract: A method for secure comparison of encrypted symbols. According to one embodiment, a user may encrypt two symbols, share the encrypted symbols with an untrusted third party that can compute algorithms on these symbols without access the original data or encryption keys such that the result of running the algorithm on the encrypted data can be decrypted to a result which is equivalent to the result of running the algorithm on the original unencrypted data. In one embodiment the untrusted third party may perform a sequence of operations on the encrypted symbols to produce an encrypted result which, when decrypted by a trusted party, indicates whether the two symbols are the same.

Abstract: Techniques for cryptographically secure, cross-domain information sharing are described. A first information domain including a first attribute-based encryption (ABE) authority defines a first universe of ABE attributes. Plaintext is encrypted using ABE encryption, producing ABE ciphertext. The ABE encryption uses an ABE access control expression defined with a set of ABE attributes comprising a first ABE attribute subset from the first universe of ABE attributes and second ABE attribute subset from a second universe of ABE attributes defined by a second ABE authority of a second information domain. The ABE ciphertext and the ABE access control expression are combined to produce an ABE package. The ABE package is encrypted, using predicate-based encryption (PBE), producing a PBE ciphertext. The PBE encryption uses a first set of PBE attributes from a universe of PBE attributes defined by a PBE authority.

Abstract: A reconfigurable aperture includes a plurality of metallic particles confined to a volume extending across an aperture area. The metallic particles are repositioned within the volume to form opaque regions in the aperture area.

The reconfigurable zone plate can effectively collimate microwaves produced by the microwave source, can direct the collimated microwaves in a specified direction, can receive microwaves returning along the specified direction, and can focus the received microwaves onto the detector.

Abstract: A method for detecting instances of exfiltration by an application. The method includes performing a first set of runs on a first computation device, and performing a second set of runs on a second computation device. Each set of runs involves running the application a plurality of times; and for each run, capturing packets transmitted by the computation device. In some embodiments the packets within the first set of runs are compared to identify differences caused by environmental noise, such as run-to-run changes in the information sent to the first device by remote servers. Comparisons between (i) runs performed on the first device and (ii) runs performed on the second device, with differences caused by environmental noise removed, may then be used to assess whether the application exfiltrates personal information, such as a phone number, that has different values on the first device and on the second device.

Abstract: A detector for detecting single photons of infrared radiation or longer wavelength electromagnetic radiation.

The voltage pulse is detected by the pulse detector.

Abstract: Embodiments described herein relate to generating an image of an acoustic field associated with an underwater region. A plurality of submersible sensing devices (SSDs) are disposed so as to be substantially separate from each other in an underwater region, wherein each respective SSD is configured to execute a sink/float mission. During at least a portion of the sink/float mission, within each SSD, an environmental sensor measures at least one environmental parameter, a position sensor detects position information, an acoustic detection sensor detects at least one underwater signal, and a data recording system records mission data. After the sink/float mission, a processor receives mission data from the SSDs and generates an acoustic field image. Advantageously, during the sink/float mission some SSDs can transmit an orthogonal high time-bandwidth signal to help prevent interference between SSD during acoustic detection.

Abstract: A system, device, and method are provided to control dense-mode multicast traffic across a multilayer system containing an upper network and a tunnel across a lower network. An upstream multicast tunneling edge device (MTED) may indicate to downstream MTEDs, via control messages, the presence of a multicast source, group (SG) pair. The MTEDs may serve as routers or as intelligent bridges in the upper network. Each downstream MTED may create a forwarding state for the SG pair, determine tunnels for which the downstream MTED is to serve as an exit device and configure the tunnels to deliver the traffic. Lower network MTEDs of a tunnel may determine whether to transport multicast data for each SG pair such that multicast traffic routed by a corresponding MTED is carried. An MTED may be able to receive, through the tunnel, multicast traffic for one SG pair even after pruning itself for another SG pair.
