  • Self-Destructing Circuits and More Security Schemes February 28, 2024
    Last week at the IEEE International Solid-State Circuits Conference (ISSCC), researchers introduced several technologies to fight even the sneakiest hack attacks. Engineers invented a way to detect a hacker placing a probe on the circuit board to attempt to read digital traffic in a computer. Other researchers invented new ways to obfuscate electromagnetic emissions radiating […]
