This reference work describes comprehensively, compactly and precisely the history, properties, production and application of all elements of the periodic table. Particular attention is paid to the chemical compounds of the elements, which are also presented extensively. This book contains 23 chapters, each of which includes the elements in the form of subchapters.

This book reveals the essence of endogenous or internal contradictions in cyberspace security issues, systematically expounds the principle of cyberspace endogenous security and safety, introduces the author-invented dynamic heterogeneous redundant (DHR) architecture with endogenous security and safety features, and theoretically answers why DHR endogenous security and safety architecture can enable network resilience engineering; the enabling role of DHR architecture solves the problem that network resilience cannot cope with unknown damage, lacks structural gain, and cannot quantify design measures. This book analyses the systematic security gains that DHR architecture enabling network resilience engineering can bring in the four purpose dimensions of prevention, defense, recovery and adaptation; gives an application example of DHR endogenous security and safety architecture enabling network resilience engineering; introduces the research and exploration of endogenous security and safety theory in wireless communication security, artificial intelligence security and other derivative application fields; and uses rich application examples. It shows that the endogenous security and safety architecture enabling network resilience engineering not only is very necessary but also has universal application significance. This book is suitable for postgraduate teaching materials or reference books of related disciplines, such as cybersecurity, network resilience engineering, confidential computing/trusted computing, information physical systems/industrial control, etc.
