Joseph Rochefort, born OTD in 1900, was a major figure in the US Navy's cryptographic and intelligence operations from 1925 to 1946, particularly in the Battle of Midway https://cromwell-intl.com/travel/japan/wwii-cryptanalysis/?s=mb #cybersecurity #cryptography #history

In a Muskian Cybercoup, Mr. Big Balls parades into your server room, and copies all of your data. It is the ultimate (quasi-)insider threat.

What can you do to protect yourself against such an adversary? You can collect less data, especially focused on reducing the collection of the most sensitive bits of data.

You can have in place retention policies that involve deleting most of the data that you do collect after a period of time.

And you can salt your password hashes with self-documenting plaintext tags, so that anybody who knows how to crack your passwords must know how to contact your organization:

Cryptohack. Решение Oh SNAP. Атака Флюрера-Мантина-Шамира (Fluhrer, Mantin, Shamir)

Приветствую, Хабр! В нескольких предыдущих статьях я рассматривал различные режимы шифрования для блочных шифров, постепенно сдвигаясь в сторону режимов, превращающих блочные шифры в потоковые. В новой статье в фокусе будет чисто потоковый шифр - RC4. Я расскажу о самом шифре, а также об атаке FMS и применении её для решения задачи Oh, SNAP с платформы Cryptohack.

Today is Joseph Rochefort's birthday! Time to learn about #cryptography https://cromwell-intl.com/cybersecurity/crypto/?s=mb #cybersecurity

I think one of the biggest problems of #society is that we're assuming (and I believe this is a reflection of #christianity) that there can only be ONE source of truth. And truth tables in order to be true or false, needs two other things to validate the truth. If one #ai says a thing, and another says a completely different thing, overlaid which thing is true? Well, there's always going to be _some_ truth in everything, and those are the markers of truths. I think #cryptography is good for that

The German submarine U-110 was captured by the Royal Navy OTD in 1941, it was carrying the latest Enigma machine which Allied cryptographers later used to break encrypted German messages https://cromwell-intl.com/travel/uk/bletchley-park/?s=mb #travel #cryptography #history

I spent some time today working on the (incomplete) design document for the Global Password Prehash Protocol, version 2. Not a lot in terms of new material, but I did reorganize things and am much happier with the overall flow at this point in time.

Last week four new #chatmail relays popped up from four different continents from four different entities.
Permission-free interoperability based on #cryptography ... That's how we like it and how it generally is with the email system: separation of transport and apps. App developers can't access messages, and relay operators can not break e2ee encryption. Fwiw May 14th there is another round at a #Moscow court where our lawyers will convey this impossibility for #deltachat to hand over data.
