Backup PNT methods are essential for GPS-denied environments - Story

November 09, 2016
Backup methods of position, navigation, and timing (PNT) are essential for warfighters operating within GPS-denied environments. Warfighters rely on the U.S. NAVSTAR global positioning system (GPS) and global navigation satellite system (GNSS) for military operations, but are encountering an intense escalation of jamming and spoofing attacks.

Managing COTS obsolescence for military systems - Story

September 12, 2016
The short life cycles of commercial components create many obsolescence headaches for military electronic-system designers as they try to integrate these high-performance devices into air, ground, and sea platforms that must last for decades, have long system development cycles, and require time-consuming testing procedures. As the military looks to leverage more open architectures and commercial off-the-shelf (COTS) technology, the challenge of managing the obsolescence that comes with COTS will only become more difficult.

Paving the way for fast, secure quantum communications - Story

June 14, 2016
Quantum key distribution (QKD) will play a central role in the next generation of secure communications, and new software from university researchers helps quickly evaluate security protocols for QKD.
Unmanned

Small UAS payloads pose SWaP and bandwidth challenges - Story

April 14, 2016
The payloads of military unmanned aircraft systems (UASs) continue to evolve - using smarter sensors and a smaller overall footprint - but must overcome size, weight, and power (SWaP) design hurdles, as well as slower-than-desirable sensor processing, lack of bandwidth in downlinks, and security challenges.

Cybersecurity: Automate cyber defense with AI reasoning? - Other

April 04, 2016
Is it possible to automate the cyber defense process with machines that can discover, confirm, and fix software flaws in real-time? The U.S. Defense Advanced Research Projects Agency (DARPA) certainly hopes so and is hosting its Cyber Grand Challenge?s (CGC) final competition in August 2016 in conjunction with DEF CON, home of the longest-running attack/defend Capture the Flag global competition for elite hackers, in Las Vegas, Nevada, to find out.
