A new paper presents a polynomial-time quantum algorithm for solving certain hard lattice problems. This could be a big deal for post-quantum cryptographic algorithms, since many of them base their security on hard lattice problems. A few things to note. One, this paper has not yet been peer reviewed. As this comment points out: “We had already some...

This is a current list of where and when I am scheduled to speak: I’m speaking twice at RSA Conference 2024 in San Francisco. I’ll be on a panel on software liability on May 6, 2024 at 8:30 AM, and I’m giving a keynote on AI and democracy on May 7, 2024 at 2:25 PM. The list is maintained on this page.

It’s a pretty awful story. As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered. Read my blog posting guidelines here.

Someone got caught trying to smuggle 322 pounds of gold (that’s about 1/4 of a cubic foot) out of Hong Kong. It was disguised as machine parts: On March 27, customs officials x-rayed two air compressors and discovered that they contained gold that had been “concealed in the integral parts” of the compressors. Those gold parts had also been painted...

Last week, the internet dodged a major nation-state attack that would have had catastrophic cybersecurity repercussions worldwide. It’s a catastrophe that didn’t happen, so it won’t get much attention—but it should. There’s an important moral to the story of the attack and its discovery: The security of the global internet depends on countless obscure...

Last week I posted a short memorial of Ross Anderson. The Communications of the ACM asked me to expand it. Here’s the longer version. EDITED TO ADD (4/11): Two weeks before he passed away, Ross gave an 80-minute interview where he told his life story.
