DE CIFRIS SEMINARS

De Componendis Cifris APS was formally established only in December 2022, but it has been active for many years in meetings and events. One of its initiatives has been the organization of many seminars. It is therefore fitting that a Koine book collects some of our best seminars. Some results may be outdated, but the papers still provide valuable insights into many areas of cryptographic research and also serve as nice introductions. The volume concludes with two interesting and original contributions. We believe that the volume’s editors, Danilo Bazzanella, Giulio Codogni, Nadir Murru and Roberto Zunino, have done a great job in selecting an interesting sample of seminars and two invited papers: isogeny-based post-quantum cryptography and integer factorization.
