This monograph illustrates important notions in security reductions and essential techniques in security reductions for group-based cryptosystems. Using digital signatures and encryption as examples, the authors explain how to program correct security reductions for those cryptographic primitives. Various schemes are selected and re-proven in this book to demonstrate and exemplify correct security reductions. This book is suitable for researchers and graduate students engaged with public-key cryptography.

This book constitutes the refereed proceedings of the 24th Australasian Conference on Information Security and Privacy, ACISP 2019, held in Christchurch, New Zealand, in July 2019. The 32 revised full papers and 8 short papers presented were carefully revised and selected from 129 submissions. The papers present and discuss the latest research, trends, breakthroughs, and challenges in the domain of information security, privacy and cybersecurity on a variety of topics such as encryption; post-quantum security; cryptocurrency related; foundations; system and network security; and symmetric cryptography.
