Galois and Dan Boneh of Stanford offer Talaria, a research project and prototype architecture of a secure, decentralized messaging and transaction platform. Talaria addresses four concerns for such platforms: resilience, scalability, security, and transparency.Talaria uses a decentralized, redundant, and distributed server-side architecture to provide resiliency. Talaria provides scalability by us ...

To meet the U.S. military need for a near-single-photon low-light-level passive imager, a large-format, near-infrared (NIR)-sensitive silicon single-photon avalanche-diode (SPAD) digital imager capable of high-dynamic range, high detection efficiency, and low dark counts will be developed. Toward this end, in Phase I, a 256 x 256-element SPAD imager will be integrated into a camera, characterized, ...

Voice phishing (vishing) has become a serious threat. Attackers pose as trusted callers using impersonation, voice mimicry, speech synthesis, voice conversion technologies, and many other techniques. Once victims believes they are speaking with a t...

Non-oxide based ceramic matrix composites (CMCs), such as Silicon Carbide and Carbon-Carbon, are current state-of-the-art (SOA) refractory thermal protection system (TPS) materials for space reentry vehicle leading edge components and hot structures that...

Touchstone Research Laboratory (TRL) has identified acetate fibers with structural characteristics analogous to heritage viscose rayon, which suggests they will be very promising Carbon Cloth Phenolic (CCP) reinforcements for Solid Rocket Motor (SRM) nozzles. Furthermore, acetate fibers are manufactured in the United States and are commercially available and deemed sustainable. Accordingly, TRL, ...

Under this Phase I effort, Stephens & Cross Research, Inc. (SCR) will demonstrate technical feasibility of a rocket inductive link using NFC technology with essential performance features of: bidirectional data communication, inductive energy harvesting and energy storage for operation during link and immediately after, and operation with conductive obscuration. Inductive link performance will be ...

To address the need for 1-m^2, scaled, cost-effective hogel optics, scalable inkjet-print additive manufacturing of three-dimensional freeform gradient-index nanocomposite hogel optics will be demonstrated. Using inkjet-print manufacturing, a series of prototype diffraction-limited achromatic gradient-index lensletssized from 100 microns to 3 mm, and configured in gradient-index hogel arrays up to ...

To improve radome materials, design approaches, and manufacturing methods, in this Phase II SBIR effort, Voxtel will optimize low-loss wave-impedance-tunable and complex-dielectrically-tunable nanocomposites and will demonstrate highly reliable additive-manufacturing (AM) methods for fabricating radomes with heterogenous compositions and complex geometries. Proof-of-concept planar and complex-geom ...

We propose software brittleness as a layer of cyber-defense in depth for software systems. Brittle programs crash quickly when under attack, which helps prevent attackers from subverting systems through security flaws. We use binary rewriting to add brittleness to programs, providing low overhead security to both legacy and newly-developed systems. Brittleness is a property of programs that provid ...

Developing secure cryptography to meet the constraints of a given application is currently a difficult, time-consuming, and error-prone process. Therefore, it is important to have automated and trustworthy tools to help easily explore the security properties of an algorithmic design space and select the variants in that space with the best combination of security and non-functional properties. Rec ...
