  1. Fun swag from the Applied Crypto Symposium today. No billiards analogies, though.

  2. I'm excited to see the two most interesting combination of color choices in the NBA tonight: the court at Barclays Center and the jerseys of the Miami Heat. Do others make their passive recreation choices based on aesthetics?

  3. At , just announced definitively that will ship end-to-end encryption in Messenger. Bold. No timeline was provided, however.

  4. All on Deck! Joan Daemen, Seth Hoffert, (from ) Permutation-based cryptography is an alternative to tweakable block ciphers. They have beyond-birthday-bound security and simple security analyses, preventing issues like that in OCB2.

  5. Attacks only get better: The case of OCB2 by Tetsu Iwata Multiple practical attacks on the OCB2 cipher mode (which is an ISO standard). An active adversary can create universal forgeries and do full plaintext recovery. Broken proof.

  6. Third, Deco: Liberating Web Data Using Decentralized Oracles for TLS presented by and . This one is far out. It lets you prove statements about data accessed over TLS without revealing the data. Useful for smart contracts.

  7. Second: The 9 Lives of Bleichenbacher's CAT: New Cache ATtacks on TLS Implementations by and others. Bleichenbacher's 1998 attack on RSA (with PKCS#1 v1.5) strikes again, this time using microarchitectural side channels.

  8. First talk: The Era of TLS 1.3: Measuring Deployment and Use with Active and Passive Methods by Johanna Amann (presenting) et al. Rapid and early adoption among big players on the server (Facebook, Google, Cloudflare) and client-side (browsers, mobile), slower in the long tail.

    goat eye glasses!

  11. Let’s improve the discourse on Twitter. If you’re constantly attacking people or groups online (subtly or directly) rather than listening and engaging in constructive discussions, it might be time to take a hard look at yourself.

  12. As promised, we've open-sourced the code behind , cfnts. It's written in Rust 🦀. Learn about how NTS works and the design of cfnts in this technical blog post by & : Contribute here:

  13. We deployed two post-quantum (aka quantum-resistant as far as we know) key agreement algorithms in TLS 1.3: one fast with big keys (ostrich) and one slow with smaller keys (turkey) and ran an experiment with Chrome to race them. Here are the results.

    This was a good one. The story was the basis for a great episode of Game of Zones:

  15. Odgovor korisnicima

    I added a screenshot of my browsing history to demonstrate how DNS leaks reveal personal information.

  16. Emma Dauterman going into detail about the True2F project at the Crypto Talk Series.

  17. An example of the difference between the British and North American uses of the word "quite" (from the reviewer criteria for RWC submissions).

  18. We made a trip out to see I Magma by at . I now see ’s lava wall from a different perspective. I would love to collaborate on a future project. Thanks, for the pix.

  19. "How does mysticism and psychedelia influence technology? I Magma is inspired by Cloudflare’s Wall of Entropy but instead of generating randomness, the work looks for patterns, signs or meaning in the lava in motion." At the Serpentine Galleries in London.
