Today, Jo Grady, general secretary of my university trade Union (UCU) wrote these words to all academic staff who are members of the union: “we are asking you to withdraw, where possible, from activities relating to the REF […] […] These activities are important to employers but they damage our sector. They rely on inappropriate …
Exactly 30 years ago, Stasi was dissolved. 13 January 1990. 91,000 full time employees and 189,000 unofficial collaborators and informants lost their jobs and privileges. The German government has done a lot to preserve anything which Stasi has ever done. Some links: At this moment in Brussels, inside the EU Parliament there is an exposition on this …
A new documentary tells the story of the discovery of one of the most important cryptography papers of all times. We are talking about an extensive technical report written in German language and entitled “Kurzgefasste Darstellung der Auflösungsmethoden”. For some 80 years it has remained classified, part of the so called Gustave Bertrand WW2 archives. It was …

In 2004 I have published a paper [Crypto 2004, Santa Barbara] in which I explain the concept of the so called Bi-Linear attack on DES. The old attack was not extremely strong. It is possible to see that two conditions would be necessary for such an attack to somewhat work well in cryptanalysis of DES: There …

A shameful provocation and sad day for scientific research: 11 years after the original publication Craig Wright has managed to re-publish Satoshi’s original paper with his name on it.
There is abundant literature on the security of Data Encryption Standard (DES or 3DES). Today we have released a new way to attack this cipher, see Section 11 in here. Anyone who reads this paper should immediately see that the high confidence which have developed over decades in research community about our ability to design secure block …

A bug which allows unlimited creation of coins was found and fixed in ZeroCash. It is a sophisticated and subtle security flaw. We read that: To exploit the counterfeiting vulnerability, an attacker would have needed to possess information found in the large MPC protocol transcript that was made available shortly after the launch of Zcash. …

George Soros decided in his old days to pick up a new fight. Let us be clear about who is George Soros. This man represents simultaneously what is the best and what is possibly the worst, inside our barely democratic Western pseudo-liberal but generally still rather free world (for now). Wisdom and great intelligence, great sensibility …
On January 3rd we celebrate 10 years since bitcoin network started operation. Long live all crypto currencies, especially those which actually are real innovators, and bring new technology such as advanced crypto techniques to the market. Let a thousand crypto flowers bloom. P.S. It is also 20 years and 2 days after the introduction of …
Spontaneous discrete protest movement of an individual against the mafias which are in charge of cyber-security, cryptography research and education at large worldwide. Students asked me what is my protest against and I have responded: It is against hate. All the hate you receive because you are different and you don’t have the same ideas …
