This book constitutes the refereed proceedings of the 11th International Conference on the Theory and Application of Cryptographic Techniques in Africa, AFRICACRYPT 2019, held in Rabat, Morocco, in July 2019. The 22 papers presented in this book were carefully reviewed and selected from 53 submissions. The papers are organized in topical sections on protocols; post-quantum cryptography; zero-knowledge; lattice based cryptography; new schemes and analysis; block ciphers; side-channel attacks and countermeasures; signatures. AFRICACRYPT is a major scientific event that seeks to advance and promote the field of cryptology on the African continent. The conference has systematically drawn some excellent contributions to the field. The conference has always been organized in cooperation with the International Association for Cryptologic Research (IACR).

This book constitutes the refereed proceedings of the 21st International Conference on Cryptology and Network Security, CANS 2022, which was held during November 13-16, 2022. The conference was took place in Abu Dhabi, United Arab Emirates. The 18 full and 2 short papers presented in these proceedings were carefully reviewed and selected from 54 submissions. They were organized in topical sections as follows: zero-knowledge and MPC; public-key infrastructure; attacks and countermeasures; cryptanalysis and provable security; cryptographic protocols; blockchain and payment systems; and codes and post-quantum cryptography.
