HISTORY OF CRYPTOGRAPHY

Organizing Committee:
  • Flavio Atzeni, Senior Web Developer
  • Paolo Bonavoglia, Independent Researcher
  • Francesco Cosimato, Retired Army General
  • Leonardo Errati, Politecnico di Torino
Description: The session explores the origins and early development of the cryptographic tools we take for granted today, from the late medieval Eu- ropean period to the dawn of modern cryptography. The workshop is designed for a diverse audience and will delve into key historical moments where cryptography and cryptanalysis played a decisive role. Special focus will be given to the emergence of analytical techniques and the gradual systematisation of cipher methods.
Speakers: Paolo Bonavoglia (Independent Researcher), Ivan Parisi (Institut Internacional d’Estudis Borgians), Marco Vito (University of Wien & University of Salerno), Flavio Atzeni (Senior Web Developer) Francesco Cosimato (Retired Army General)

QUANTUM RANDOM NUMBER GENERATORS & CRYPTOGRAPHY

Organizing Committee:
  • Massimo Caccia, RandomPower s.r.l. and University of Insubria
  • Leonardo Errati, Politecnico di Torino
  • Roberto La Scala, Università di Bari
Descritpion: We explore the role of quantum technologies in modern cryptography, presenting their physical principles, cryptographic relevance, engineering perspectives, and practical implementations. The workshop will focus on Quantum Random Number Generators (QRNG), highlighting on- going work, recent standards, and future directions. It will present theoretical motivations and practical implementations from all involved perspectives. The target audience includes cryptographers, physicists, engineers, and institutional stake- holders interested in quantum technologies and secure communications. We aim to provide an accessible and multidisciplinary perspective, fostering collaboration across fields.
