This is interesting research: In a BGP hijack, a malicious actor convinces nearby networks that the best path to reach a specific IP address is through their network. That’s unfortunately not very hard to do, since BGP itself doesn’t have any security procedures for validating that a message is actually coming from the place it … Read More “Using Machine Learning to Detect IP Hijacking” »
This theoretical paper shows how to factor 2048-bit RSA moduli with a 20-million qubit quantum computer in eight hours. It’s interesting work, but I don’t want overstate the risk. We know from Shor’s Algorithm that both factoring and discrete logs are easy to solve on a large, working quantum computer. Both of those are currently … Read More “Factoring 2048-bit Numbers Using 20 Million Qubits” »
In 1999, I invented the Solitaire encryption algorithm, designed to manually encrypt data using a deck of cards. It was written into the plot of Neal Stephenson’s novel Cryptonomicon, and I even wrote an afterward to the book describing the cipher. I don’t talk about it much, mostly because I made a dumb mistake that … Read More “More Cryptanalysis of Solitaire” »

Good paper on cybersecurity insurance: both the history and the promise for the future. From the conclusion: Policy makers have long held high hopes for cyber insurance as a tool for improving security. Unfortunately, the available evidence so far should give policymakers pause. Cyber insurance appears to be a weak form of governance at present. … Read More “On Cybersecurity Insurance” »
Interesting paper by Michael Schwarz, Samuel Weiser, Daniel Gruss. The upshot is that both Intel and AMD have assumed that trusted enclaves will run only trustworthy code. Of course, that’s not true. And there are no security mechanisms that can deal with malicious enclaves, because the designers couldn’t imagine that they would be necessary. The … Read More “Attacking the Intel Secure Enclave” »
Voice systems are increasingly using AI techniques to determine emotion. A new paper describes an AI-based countermeasure to mask emotion in spoken words. Their method for masking emotion involves collecting speech, analyzing it, and extracting emotional features from the raw signal. Next, an AI program trains on this signal and replaces the emotional indicators in … Read More “AI Emotion-Detection Arms Race” »
Interesting analysis: “Examining the Anomalies, Explaining the Value: Should the USA FREEDOM Act’s Metadata Program be Extended?” by Susan Landau and Asaf Lubin. Abstract: The telephony metadata program which was authorized under Section 215 of the PATRIOT Act, remains one of the most controversial programs launched by the U.S. Intelligence Community (IC) in the wake … Read More “Evaluating the NSA’s Telephony Metadata Program” »
Rebecca Wexler has an interesting op-ed about an inadvertent harm that privacy laws can cause: while law enforcement can often access third-party data to aid in prosecution, the accused don’t have the same level of access to aid in their defense: The proposed privacy laws would make this situation worse. Lawmakers may not have set … Read More “How Privacy Laws Hurt Defendants” »
In this piece of research, attackers successfully attack a driverless car system — Renault Captur’s “Level 0” autopilot (Level 0 systems advise human drivers but do not directly operate cars) — by following them with drones that project images of fake road signs in 100ms bursts. The time is too short for human perception, but … Read More “Another Attack Against Driverless Cars” »
