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” »
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” »
The ISO has rejected two symmetric encryption algorithms: SIMON and SPECK. These algorithms were both designed by the NSA and made public in 2013. They are optimized for small and low-cost processors like IoT devices. The risk of using NSA-designed ciphers, of course, is that they include NSA-designed backdoors. Personally, I doubt that they’re backdoored. … Read More “Two NSA Algorithms Rejected by the ISO” »

Russia has banned the secure messaging app Telegram. It’s making an absolute mess of the ban — blocking 16 million IP addresses, many belonging to the Amazon and Google clouds — and it’s not even clear that it’s working. But, more importantly, I’m not convinced Telegram is secure in the first place. Such a weird … Read More “Russia is Banning Telegram” »
Interesting idea: …we present Oblivious DNS (ODNS), which is a new design of the DNS ecosystem that allows current DNS servers to remain unchanged and increases privacy for data in motion and at rest. In the ODNS system, both the client is modified with a local resolver, and there is a new authoritative name server … Read More “Oblivious DNS” »
This is a really interesting research result. This paper proves that two parties can create a secure communications channel using a communications system with a backdoor. It’s a theoretical result, so it doesn’t talk about how easy that channel is to create. And the assumptions on the adversary are pretty reasonable: that each party can … Read More “Subverting Backdoored Encrryption” »

Seems like everyone is writing about encryption and backdoors this season. “Policy Approaches to the Encryption Debate,” R Street Policy Study #133, by Charles Duan, Arthur Rizer, Zach Graves and Mike Godwin. “Encryption Policy in Democratic Regimes,” East West Institute. I recently blogged about the new National Academies report on the same topic. Here’s a … Read More “Two New Papers on the Encryption Debate” »
