Interesting research on a version of RSA that is secure against a quantum computer: Post-quantum RSA Daniel J. Bernstein, Nadia Heninger, Paul Lou, and Luke Valenta Abstract: This paper proposes RSA parameters for which (1) key generation, encryption, decryption, signing, and verification are feasible on today’s computers while (2) all known attacks are infeasible, even … Read More “Post-Quantum RSA” »
There’s interesting research on using a set of “master” digital fingerprints to fool biometric readers. The work is theoretical at the moment, but they might be able to open about two-thirds of iPhones with these master prints. Definitely something to keep watching. Research paper (behind a paywall).

Interesting research: The radio signals emitted by a commercial Wi-Fi router can act as a kind of radar, providing images of the transmitter’s environment, according to new experiments. Two researchers in Germany borrowed techniques from the field of holography to demonstrate Wi-Fi imaging. They found that the technique could potentially allow users to peer through … Read More “Using Wi-Fi to Get 3D Images of Surrounding Location” »
I’ve previously written about ad networks using ultrasonic communications to jump from one device to another. The idea is for devices like televisions to play ultrasonic codes in advertisements and for nearby smartphones to detect them. This way the two devices can be linked. Creepy, yes. And also increasingly common, as this research demonstrates: Privacy … Read More “Using Ultrasonic Beacons to Track Users” »
In the oval squid Sepioteuthis lessoniana, males use body patterns to communicate with both females and other males: To gain insight into the visual communication associated with each behavior in terms of the body patterning’s key components, the co-expression frequencies of two or more components at any moment in time were calculated in order to … Read More “Friday Squid Blogging: Squid Communications” »
Researchers have configured two computers to talk to each other using a laser and a scanner. Scanners work by detecting reflected light on their glass pane. The light creates a charge that the scanner translates into binary, which gets converted into an image. But scanners are sensitive to any changes of light in a room … Read More “Jumping Airgaps with a Laser and a Scanner” »
There has been a flurry of research into using the various sensors on your phone to steal data in surprising ways. Here’s another: using the phone’s ambient light sensor to detect what’s on the screen. It’s a proof of concept, but the paper’s general conclusions are correct: There is a lesson here that designing specifications … Read More “Stealing Browsing History Using Your Phone’s Ambient Light Sensor” »
Interesting paper: “The rise of reading analytics and the emerging calculus of reading privacy in the digital world,” by Clifford Lynch: Abstract: This paper studies emerging technologies for tracking reading behaviors (“reading analytics”) and their implications for reader privacy, attempting to place them in a historical context. It discusses what data is being collected, to … Read More “Reading Analytics and Privacy” »
There’s a really interesting new paper analyzing over 100 different cyber insurance policies. From the abstract: In this research paper, we seek to answer fundamental questions concerning the current state of the cyber insurance market. Specifically, by collecting over 100 full insurance policies, we examine the composition and variation across three primary components: The coverage … Read More “Analyzing Cyber Insurance Policies” »
I regularly say that, on the Internet, attack is easier than defense. There are a bunch of reasons for this, but primarily it’s 1) the complexity of modern networked computer systems and 2) the attacker’s ability to choose the time and method of the attack versus the defender’s necessity to secure against every type of … Read More “Attack vs. Defense in Nation-State Cyber Operations” »
