This book constitutes the proceedings of the satellite workshops held around the 20th International Conference on Applied Cryptography and Network Security, ACNS 2022, held in Rome, Italy, in June 2022. Due to the Corona pandemic the workshop was held as a virtual event. The 31 papers presented in this volume were carefully reviewed and selected from 52 submissions. They stem from the following workshops: – AIBlock: 4th ACNS Workshop on Application Intelligence and Blockchain Security – AIHWS: 3rd ACNS Workshop on Artificial Intelligence in Hardware Security – AIoTS: 4th ACNS Workshop on Artificial Intelligence and Industrial IoT Security – CIMSS: 2nd ACNS Workshop on Critical Infrastructure and Manufacturing System Security – Cloud S&P: 4th ACNS Workshop on Cloud Security and Privacy – SCI: 3rd ACNS Workshop on Secure Cryptographic Implementation – SecMT: 3rd ACNS Workshop on Security in Mobile Technologies – SiMLA: 4th ACNS Workshop on Security in Machine Learning and its Applications

Cryptography will continue to play important roles in developing of new security solutions which will be in great demand with the advent of high-speed next-generation communication systems and networks. This book discusses some of the critical security challenges faced by today's computing world and provides insights to possible mechanisms to defend against these attacks. The book contains sixteen chapters which deal with security and privacy issues in computing and communication networks, quantum cryptography and the evolutionary concepts of cryptography and their applications like chaos-based cryptography and DNA cryptography. It will be useful for researchers, engineers, graduate and doctoral students working in cryptography and security related areas. It will also be useful for faculty members of graduate schools and universities.

This two-volume set of LNCS 12146 and 12147 constitutes the refereed proceedings of the 18th International Conference on Applied Cryptography and Network Security, ACNS 2020, held in Rome, Italy, in October 2020.The conference was held virtually due to the COVID-19 pandemic. The 46 revised full papers presented were carefully reviewed and selected from 214 submissions. The papers were organized in topical sections named: cryptographic protocols cryptographic primitives, attacks on cryptographic primitives, encryption and signature, blockchain and cryptocurrency, secure multi-party computation, post-quantum cryptography.
