John Haas and Christian Baumann, two blog readers who met when I invited both of them to a get-together in Vienna, have started an interesting project.
A French expert team has succeeded in factorizing a 795 bit prime number product. This is a new world record. The old one (768 bit) dated from 2009.
IT security experts have cracked a number of passwords used by Unix pioneers in the late 1970s.
At the NSA Symposium on Cryptologic History, I will give a presentation about brute-force attacks. There’s one thing I still haven’t figured out: when was the first brute-force described or carried out?
In the early 1970s, cryptographers in the USA and in East Germany developed two suprisingly similar encryption methods. Did one party steal from the other? Or was a useful concept invented twice?
In 1999 cryptographer Ron Rivest published an encrypted text that was designed to take 35 years to break. Apparently, it has now been solved.
US standardization authority NIST has published the algorithms that participate in the Post-Quantum Crypto Competition. No fewer than 69 crypto systems enter the race.
Today I am going to introduce a simple asymmetric encryption system. It’s not suitable for practical use, but very helpful for explaining how public key cryptography works.
Researchers tested whether two artificial intelligence systems could develop an ecryption algorithm a third one could not break. In some test runs it worked.
