Last month, Wired published a long article about Ray Ozzie and his supposed new scheme for adding a backdoor in encrypted devices. It’s a weird article. It paints Ozzie’s proposal as something that “attains the impossible” and “satisfies both law enforcement and privacy purists,” when (1) it’s barely a proposal, and (2) it’s essentially the … Read More “Ray Ozzie’s Encryption Backdoor” »

Interesting symmetric cipher: LC4: Abstract: ElsieFour (LC4) is a low-tech cipher that can be computed by hand; but unlike many historical ciphers, LC4 is designed to be hard to break. LC4 is intended for encrypted communication between humans only, and therefore it encrypts and decrypts plaintexts and ciphertexts consisting only of the English letters A … Read More “LC4: Another Pen-and-Paper Cipher” »

This is interesting: Creating these defenses is the goal of NIST’s lightweight cryptography initiative, which aims to develop cryptographic algorithm standards that can work within the confines of a simple electronic device. Many of the sensors, actuators and other micromachines that will function as eyes, ears and hands in IoT networks will work on scant … Read More “NIST Issues Call for “Lightweight Cryptography” Algorithms” »

Researchers at Princeton University have released IoT Inspector, a tool that analyzes the security and privacy of IoT devices by examining the data they send across the Internet. They’ve already used the tool to study a bunch of different IoT devices. From their blog post: Finding #3: Many IoT Devices Contact a Large and Diverse … Read More “IoT Inspector Tool from Princeton” »
