Title: The Enigma Relay. A Discovered Report of Polish Cryptologists.

Abstract: The secret of Enigma has never been Clio's favorite. The first Allied accounts from the meeting in Pyry were dictated by emotions rather than by concern for the truth. Post-war reports on Bletchley Park were written down by people whose knowledge of the role of Poles had been at best second- or third-hand. When the secret was revealed in 1973, the British and Americans considered it premature and surrounded the history of breaking Enigma with a thick layer of disinformation, which was then picked up by historians and then by authors of dramatic fiction and film screenplays. Therefore, it is a pity that the document which is the most complete summary of the Polish contribution to the breaking of Enigma, the report passed on to the Allies in July 1939, still remains inaccessible to historians. Fortunately, a document was found in the French archives, which probably constituted an abridged version of the Pyry report. Its contents allows us to verify the contribution of the British, French and Polish codebreakers in the triumph over Enigma and to summarize the earliest period of Allied cooperation in cryptology.

Title: The hidden discovery of public key cryptography.

Abstract: In my talk I will discuss the discovery of public key cryptography at Government Communications Headquarters in England during the period 1969 to 1974. The discoveries, which were called at the time “non-secret encryption” and were not disclosed publicly, remarkably parallel the later discoveries of Diffie and Hellman, and those of Rivest, Shamir and Adleman.

Medals of Adam Mickiewicz University in Poznań for Marian Rejewski, Jerzy Różycki and Henryk Zygalski.

Medal Alumno bene merenti of Adam Mickiewicz University in Poznań, established by the resolution of the UAM Senate in September 2016, is awarded to the most outstanding graduates of the University. On the occasion of the 85th anniversary of breaking the Enigma code, the medal was posthumously awarded to the most famous Polish cryptologists: Marian Rejewski, Jerzy Różycki and Henryk Zygalski.

On January 25, 2018, the Alumno bene merenti medal ceremony will be held in the Lubranski Hall of Collegium Minus. The ceremony is part of the next Cryptology Day at AMU, a special edition of the annual Marian Rejewski, Jerzy Różycki and Henryk Zygalski Lectures in Computer Science. Exactly ten years ago, the first Cryptology Day inaugurated this series of lectures established by the resolution of the Council of the Faculty of Mathematics and Computer Science in connection with the 75th anniversary of the victory over the Enigma. During these ten years, lectures were given by: Marek Grajek, Andrew Odlyzko, Józef Pieprzyk, Avi Wigderson, Emo Welzl, Shafi Goldwasser, Johan Hastad, Noga Alon, Gil Kalai, Dermot Turing, Christos H. Papadimitriou. Already the lecture cycle has become world-class, as these names clearly attest.

On January 25, 2018, during the second Cryptology Day, lectures of Marek Grajek (The Enigma Relay. A Discovered Report of Polish Cryptologists) and Clifford Cocks (The Hidden Discovery of Public Key Cryptography) will be delivered.

Speakers

Dr Marek GrajekDr Marek Grajek is a consultant on cryptology's application in financial turnover and in capital markets. He was an initiator of the erection of a statue recalling Polish cryptographers' merits located in Poznań as well as an author of many other initiatives related to them. His book "Enigma. Bliżej prawdy", summing up the history of Enigma's decipherings and describing the machine's influence on the World War II, won a best history book contest in 2008. Marek Grajek is also an author of other books and elaborations, such as "Narodziny kryptologii matematycznej" (with Leszek Gralewski), "Maksymilian Ciężki: 1898-1951" (with Barbara Ciężka), "Nie tylko Enigma: Ryba, która przemówiła". Ten years ago, on 25 January 2008, Marek Grajek opened a series of Rejewski, Różycki, Zygalski lectures giving a talk entitled „Guardians of Lies".

Clifford Christopher Cocks is a British mathematician and cryptologist. He studied in Profesor Clifford CocksCambridge, and after graduating - in Oxford. In 1973 he left Oxford to work for the British government in GCHQ, where in 2003 he became Chief Mathematician. He has also established the Heilbronn Institute for Mathematical Research at the University of Bristol. He has received honorary degrees from the univerisites of Bristol, East Anglia and Birmingham. In 2008 he was made a Companion of the Order of the Bath. In 2010 he was awarded the milestone prize by the Institute of Electrical and Electronics Engineers (IEEE) with James Ellis and Malcolm Williamson. In 2015 he was elected a Fellow of the Royal Society. His research focuses on mathematics and cryptography. In September 1973, during his work at GCHQ, he has invented a public-key algorithm identical to the one published by Rivest, Shamir and Adelman several years later (the RSA algorithm). However, his discovery has been classified, and remained so until 1997. In 2001 Clifford Cocks has developed one of the first identity-based publick key encryption schemes.
