  • GPS Jamming? No Problem, LEO Satellites Hold the Key to Resilient, Interference-Free Navigation

    Increasingly occurring GPS jamming disrupts the daily civilian activities, posing major navigational challenges. A new method using Low Earth Orbit (LEO) satellites and massive Multiple Input Multiple Output (MIMO) antennas addresses these location vulnerability issues, presenting means for precise navigation even where traditional global navigation satellite systems (GNSS) fail.

  • Pagers and Walkie-talkies Over Cellphones – a Security Expert Explains Why Hezbollah Went Low-Tech for Communications

    In general, I believe the adversary in an asymmetric conflict using low-tech techniques, tactics and technology will almost always be able to operate successfully against a more powerful and well-funded opponent. But from a cybersecurity perspective, Israel’s attack on Hezbollah’s pagers shows that any device in your life can be tampered with by an adversary at points along the supply chain – long before you even receive it.

  • Why Experts Are Calling for a New Strategy to Improve U.S. Access to Semiconductors ― The Technology that Underpins Artificial Intelligence

    While the U.S. first developed semiconductors and led globally in semiconductor development and manufacturing in the last century, today it produces just 12% of all semiconductors. A new report from the National Academies recommends actions for the U.S. Department of Defense ― coordinating with the commercial sector, universities, and other parts of government ― to secure its access to this critical technology.
