Later today, I am finally going to live-present a conference paper again: "Anonymously Publishing Liveness Signals with Plausible Deniability", mostly by Michael Sonntag and in cooperation with Stefan Rass and me. The topic is a cryptographic protocol for verifying that whistleblowers and other secrets holders are still alive and well, that is, generating and verifying binary signals (without further information content) sent (semi-) regularly.

The most interesting aspects follow from the goal of plausible deniability: as a prover (whisteblower) or verifier, being able to plausibly claim to hold the respective other role or being part of an interaction that has already become inactive before, because stored data does not allow deciding either way when provided with the wrong decryption passphrase. Tools we use are Tor onion services and hash chains (totally not a Blockchain), prototyped as a Java library and Android app.

So there is a lack of accessibility to folks in the #GlobalSouth in particular. These Motorolas cost around half of what the budget versions of Pixel phones cost and are sold in many countries in continents where Pixels are not, including in #SouthAmerica #Asia and #MENA

Thank you to #StartSmall and jack dorsey for believing in us, and for the funding that made this possible ! And a BIG thank you to our friends at @LineageOS for their work on platform support for the Motorola phones

Huge announcement ! @calyxos is now available for the Motorola G32, G42 and G52 ! Why is this a big deal ? Because it helps us further our mission of making #PrivacyByDesign available to the maximum amount of people around the world as we can..

Google Pixel phones are the default and easiest phones to support while maintaining the #Android security model with a locked boot loader and full verified boot. But they are only sold in around a dozen countries around the world...

EFF's latest report shows that many of the internet's ills have one thing in common: they're based on the business model of widespread corporate surveillance online. https://www.eff.org/deeplinks/2023/11/address-online-harms-we-must-first-do-privacy

Oh, and lastly, this whole Mastodon thread as a much more convenient blog post 😜:

I just started a thread on Hacker News about Encrypted Client Hello (ECH):

Feel free to comment either here or there.

I hacked some ECH (encrypted client hello) support in the JDK network stack the other day (in TLS 1.3).

Hey, so #RFC9460 HTTPS/SVCB records are neat, right?

They...
- speed up your time-to-first-packet (by basically stuffing the Alt-Svc HTTP header / ALPN TLS extension into the #DNS);
- let you do redirection on the zone apex without using CNAMEs;
- allow for simple DNS load distribution and failover;
- obviate HSTS and the cumbersone preloading process;
- enable stronger privacy protections via Encrypted Client Hello aka #ECH

Mozilla is ringing the alarm bell on a dangerous EU regulation.
