Bent Functions

“This book is a very significant contribution to the theory of bent functions and will be useful to advanced students and researchers interested in cryptographic Boolean functions.” (Sugata Gangopadhyay, Mathematical Reviews, October, 2017)“This book is a comprehensive and very detailed collection of results on bent functions obtained in the decades after their introduction. … The book is addressed to researchers in discrete mathematics and their applications in cryptography or coding theory. It can serve as a comprehensive reference book on topics on (Boolean) bent functions. Furthermore it is interesting for theoretical computer scientists or engineers.” (Wilfried Meidl, zbMATH 1364.94008, 2017)
