This book constitutes the proceedings of the 5th International Symposium on Cyberspace Safety and Security, CSS 2013, held in Zhangjiajie, China, in November 2013. The 30 full papers presented in this volume were carefully reviewed and selected from 105 submissions. In addition the book contains 6 workshop papers. The papers are organized in topical sections named: data and applications security; network and communications security; software and systems security; and cloud security and cyberspace safety.

This book focuses on the different representations and cryptographic properties of Booleans functions, presents constructions of Boolean functions with some good cryptographic properties. More specifically, Walsh spectrum description of the traditional cryptographic properties of Boolean functions, including linear structure, propagation criterion, nonlinearity, and correlation immunity are presented. Constructions of symmetric Boolean functions and of Boolean permutations with good cryptographic properties are specifically studied. This book is not meant to be comprehensive, but with its own...
