Improving the Cryptanalysis of Lattice-Based Public-Key Algorithms

The winner of the Best Paper Award at Crypto this year was a significant improvement to lattice-based cryptanalysis. This is important, because a bunch of NISTs post-quantum options base their security on lattice problems. I worry about standardizing on post-quantum algorithms too quickly. We are...

A Hacker’s Mind is Out in Paperback

The paperback version of A Hackers Mind has just been published. Its the same book, only a cheaper format. But--and this is the real reason I am posting this--Amazon has significantly discounted the hardcover to $15 to get rid of its stock. This is much cheaper than I am selling it for, and cheap...

No, Toothbrushes Were Not Used in a Massive DDoS Attack

The widely reported story last week that 1.5 million smart toothbrushes were hacked and used in a DDoS attack is false. Near as I can tell, a German reporter talking to someone at Fortinet got it wrong, and then everyone else ran with it without reading the German text. It was a hypothetical, whi...

On Software Liabilities

A Self-Enforcing Protocol to Solve Gerrymandering

In 2009, I wrote: There are several ways two people can divide a piece of cake in half. One way is to find someone impartial to do it for them. This works, but it requires another person. Another way is for one person to divide the piece, and the other person to complain to the police, a judge, o...

Facebook’s Extensive Surveillance Network

Consumer Reports is reporting that Facebook has built a massive surveillance network: Using a panel of 709 volunteers who shared archives of their Facebook data, Consumer Reports found that a total of 186,892 companies sent data about them to the social network. On average, each participant in th...

CFPB’s Proposed Data Rules

Chatbots and Human Conversation

For most of history, communicating with a computer has not been like communicating with a person. In their earliest years, computers required carefully constructed instructions, delivered through punch cards; then came a command-line interface, followed by menus and options and text boxes. If you...

Quantum Computing Skeptics

Interesting article. I am also skeptical that we are going to see useful quantum computers anytime soon. Since at least 2019, I have been saying that this is hard. And that we dont know if its "land a person on the surface of the moon" hard, or "land a person on the surface of the sun" hard. They...

Zelle Is Using My Name and Voice without My Consent

Okay, so this is weird. Zelle has been using my name, and my voice, in audio podcast ads--without my permission. At least, I think it is without my permission. Its possible that I gave some sort of blanket permission when speaking at an event. Its not likely, but it is possible. I wrote to Zelle...

Speaking to the CIA’s Creative Writing Group

This is a fascinating story. Last spring, a friend of a friend visited my office and invited me to Langley to speak to Invisible Ink, the CIAs creative writing group. I asked Vivian not her real name what she wanted me to talk about. She said that the topic of the talk was entirely up to me. I...

Facial Scanning by Burger King in Brazil

Now, computer...

AI Is Scarily Good at Guessing the Location of Random Photos

Wow: To test PIGEONs performance, I gave it five personal photos from a trip I took across America years ago, none of which have been published online. Some photos were snapped in cities, but a few were taken in places nowhere near roads or other easily recognizable landmarks. That didnt seem to...
