[en] Signal #messenger: "two practical attacks that break the integrity properties of #Signal in its advertised #threat model" - Patched
Paper #ETHZ
"... protocol for resolving identities based on usernames and on phone numbers introduced a #vulnerability that allows a malicious server to inject arbitrary messages into one-to-one conversations under specific circumstances"
"The second #attack is even more severe. It arises from Signal's Sealed Sender (SSS) feature, designed to allow sender identities to be hidden ... a combination of two errors in the #SSS implementation in #Android allows a #malicious server to #inject arbitrary messages into both one-to-one and group conversations."

Is there a better system? Maybe it is the best it can be. Or not perfect still. But still it is not possible to catch every single injustice and innocents pay the price instead of the guilty. It needs improvement towards this way but it seems economy limits everything. At least there is some form of peace, people who smile, evolution, products that make life easier. But what moral person can enjoy the joys of life when justice is wrong?

Some people do not want to have sex and consider it rape. However, the system's people they all want sex. The system should keep the people in the system. The system should be just. They consider them innocent and the others guilty. But how. They all pretend to be the exact opposite and create fake evidence for the innocents.

35 years ago, Jim Sanborn presented the cryptographic sculpture Kryptos to the Central Intelligence Agency in Langley, Virginia. Made from copper, granite, quartz and petrified wood, it has four sections, each of which holds a message in code. Over the years, three of the sections have been solved — by CIA code breakers, a California computer scientist, and the National Security Agency. Now, 79-year-old Sanborn says he's going to auction off the solution to the final message, with the company arranging the sale estimating a winning bid between $300,000 and $500,000. Here's @newyorktimes's story on why he's doing it now, and what he hopes the winning bidder will do with the secret.

@rebeccawatson There actually *are* ways of performing age verification in a privacy-preserving way, thanks to zero-knowledge proof cryptography:
StRanGeLY tHoUgH, governments don't seem interested in merely knowing that a user truly is >=$some_age, and not knowing anything else about them. They really, *really* wanna know who the perverts^W adults are.

The paper I co-authored (“A Critical Analysis of Deployed Use Cases for Quantum Key Distribution and Comparison with Post-Quantum Cryptography”) was accepted for publication by “EPJ Quantum Technology” today. 😊
You can find the preprint here, Nick will eventually update it with the final changes.
In short: We looked into existing use-cases for #QuantumKeyDistribution and whether they make any sense and did so as a joint team between people with a QKD-background and cryptographers who started out very critical of QKD. (I’m firmly in the latter camp.)
My personal summary (though some of my co-authors won’t share it to this extend): #QKD is bullshit and not useful for practical purposes as it stands.

Code Warriors: NSA's Codebreakers and the Secret Intelligence War Against the Soviet Union by Stephen Budiansky, 2016
Stephen Budiansky—a longtime expert in cryptology—tells the fascinating story of how NSA came to be, from its roots in World War II through the fall of the Berlin Wall. Along the way, he guides us through the fascinating challenges faced by cryptanalysts, and how they broke some of the most complicated codes of the 20th c.
