U.S. President Joe Biden appears ready to increase pressure on Japan and the Netherlands to help block the flow of advanced chip technology to China, where it can be used to develop cutting-edge weapons. "You will see Japan and Netherlands follow our lead," U.S. Commerce Secretary Gina Raimondo told CNBC. Japan plans to budget ¥350 billion ($2.38 billion) in a research collaboration with th... » read more

Post-Quantum And Pre-Quantum Security Issues Grow
By Marie C. Baca - 03 Nov, 2022 - Comments: 2

General-purpose quantum computers will be able to crack the codes that protect much of the world’s information, and while these machines don’t exist yet, security experts say governments and businesses are starting to prepare for encryption in a post-quantum world. The task is made all the more challenging because no one knows exactly how future quantum machines will work, or even which mat... » read more
