Using Mathematics to Make Computing on Encrypted Data Secure and Practical

In order to make computing on encrypted data more practical to use and more secure from attack, it is necessary to discover, develop, and understand the mathematics on which it is based and the mathematics that can be used to attack it.

Secret Sharing Schemes and Advanced Encryption Standard

There are many secret sharing schemes and variations available to hide and reconstruct the given secret. Shamir’s Secret Sharing Scheme, making use of linear Lagrange interpolation on the dealer-generated polynomial, was used to reconstruct the secret from the stipulated threshold number of participants’ shares. Such a scheme had been widely analyzed by mathematicians and computer scientists for potential weaknesses in the reconstruction of the secret by an external eavesdropper.

Pushbroom Stereo for High-Speed UAV Navigation in Cluttered Environments

Unmanned aerial vehicles (UAVs) rely on an external motion-capture apparatus that gives the vehicles almost perfect state information at high rates. Major challenges in gathering sensing data necessary for flight are the limited payload, computation, and battery life of the vehicles. Lightweight cameras are a good solution, but require computationally efficient machine vision algorithms that can run within the limits of these vehicles.

Modeling and Simulation of an Unmanned Ground Vehicle Power System

Robotic vehicles such as unmanned ground vehicles (UGVs) have multiple sources of power, including batteries, fuel cells, combustion engines, ultracapacitors, and solar cells to allow for extended periods of operation. Fuel-based power sources have a higher specific energy than batteries, which is why most current automobiles are gasoline-powered. Batteries have many other advantages in terms of low noise profile, easy replacement, and direct energy conversion. Solar charging allows for harvesting of natural resources to increase total energy reserves. Mission duration may be maximized using a combination of power systems.

Dual-Node, Short-Depth 4U Chassis

Advantech (Irvine, CA) has launched the 4U, dual-node, short-depth (350mm), industrial chassis ACP-4D00 designed for machine automation applications that require two computers in one piece of equipment. The dual node architecture allows the user to install two half-size slot SBCs in two sub-systems and integrate them in a compact 4U cage. Each ACP-4D00 node supports a PICMG 1.3 or PCI half-size CPU card with computing power up to desktop Core™ i7, 6-slot backplane with maximum 3 PCIe or PCI expansion slots (3 slots are occupied by CPU card) and 250W or 350W high-efficiency 80 Plus power supply.

Currently Advantech offers two PICMG 1.3 CPU cards— PCE-3028 (Intel® Q87), PCE-4128 (Intel® C226), and three PICMG 1.3 backplanes—PCE-3B03-00A1E, PCE-3B06-00A1E, and PCE-3B06-03A1E, for use with ACP-4D00. The system configurations support the latest Intel® 4th generation Core™ i processors, advanced PCIe Gen 3, or legacy PCI expansions.

Virtual Environment Tool Chain

The DiSTI Corporation (Orlando, FL) has commercialized their scalable tool chain and process for producing 3-D virtual maintenance training environments. Previously only available in conjunction with DiSTI’s professional services, the Virtual Environment Software Development Kit is now productized as VE Studio and allows users to engineer their own virtual environments for maintenance training.

The foundation of VE Studio is the Fidelity Matrix, a relational database that correlates requirements, 3D objects, 2D support equipment, environment properties, and constraints that feed the automated build and testing tools. The tools that populate and reference the Fidelity Matrix include: Requirements Analyzer, an optional tool to analyze job procedures that in turn auto-populate the Fidelity Matrix with the objects and actions needed to complete the tasks; a graphical user interface for creating and modifying Fidelity Matrix content (FM Editor), a 3ds Max plug-in to associate 3-D model geometry with objects in the Fidelity Matrix (MaxLink), VE Builder, and VE Tester.
