Another Story of Bad 1970s Encryption

This one is from the Netherlands. It seems to be clever cryptanalysis rather than a backdoor. The Dutch intelligence service has been able to read encrypted communications from dozens of countries since the late 1970s thanks to a microchip, according to research by de Volkskrant on Thursday. The...

More Cryptanalysis of Solitaire

In 1999, I invented the Solitaire encryption algorithm, designed to manually encrypt data using a deck of cards. It was written into the plot of Neal Stephenson's novel Cryptonomicon, and I even wrote an afterward to the book describing the cipher. I don't talk about it much, mostly because I mad...

Cryptanalysis of SIMON-32/64

A weird paper was posted on the Cryptology ePrint Archive working link is via the Wayback Machine, claiming an attack against the NSA-designed cipher SIMON. You can read some commentary about it here. Basically, the authors claimed an attack so devastating that they would only publish a...

Weak SSL 3DES Cipher Suites (CVE-2016-2183)

3DES is a widely supported stream cipher often preferred by TLS servers and other servers using encrypted sessions. Recent cryptanalysis results one of which is the SWEET32 exploit biases in the 3DES keystroke to recover repeatedly encrypted plain-texts. As a result 3DES can no longer be seen as...
