The National Security Agency last week announced five more additions to its portfolio of technologies available to businesses for new product development.
Two of the technologies offer improved cybersecurity and the other three cover big data searches, improved geolocation, and free-space optical communications.
“These technologies are part of NSA’s portfolio of over 100 patents that are available to license,” said Linda Burger, director of the NSA Technology Transfer Program, in an email to TechLink. “Our patented technologies cover the areas of big data, cyber, internet of things, and mobility and are well suited for solutions to today’s most pressing needs. I encourage companies to review the portfolio and then contact us to leverage NSA technology and gain market advantage.”
The inventions, listed below, are available to qualified businesses who negotiate a patent license agreement with the agency after providing a commercialization plan.
TechLink, the Department of Defense’s national partnership intermediary, provides no-cost licensing assistance to businesses that seek to develop NSA technologies into new products and services.
“We help companies develop license application materials and work with the National Security Agency to develop fair terms for their technology, enabling license agreements to be established,” said Sean Patten, the senior technology manager at TechLink who works with the NSA.
To improve searches of large volumes of documents beyond the limitations of Boolean keyword searches, this NSA invention determines the relevancy of a pair of words. A training set of documents is used to determine word pair relevancy based upon a co-occurrence matrix, a probability matrix, a transition matrix and an expected search distance measure. These measures determine document relevancy in the second, live set, which are ranked accordingly.
This cryptographic technology enables validation of public keys for transmitting and receiving encrypted messages with lattice-based and other quantum-resistant protocols. It has the potential for improved security on VOIP, web browsing, and messaging services.
One of the problems of long-distance "Free Space Optics" is collecting enough signal at the detector to effectively receive data. Even if the correct wavelength of light is selected and the finest optics are used, light (even laser light) will disperse over distance due to a variety of factors including precipitation, temperature differentials, optical element stability, airborne particulates, off angle collection and effective steering. This NSA technology, coupled with a Fresnel lens, expands the receiver's size, funneling light onto the detector. It has the potential to improve laser and LED-based free space communications.
This NSA invention improves estimations of signal emitter locations by generating a polynomial approximation of a time-varying carrier frequency of a received signal by computing a cross-spectral surface of the received signal and a LaGrange polynomial interpolation. Potential applications include mobile geolocation services, rescue operations, and data communications.
