This book provides an introduction to secret sharing, a key technology for practical applications and higher-level cryptographic protocols.  This survey analyzes existing work, and systematically presents secret sharing protocols for various adversary models. It provides intuitive as well as formal descriptions of the different types of adversaries, including their computational powers and capabilities. In addition, it then offers guidance and support in selecting the appropriate type of protocol for a given application domain, present representative protocols, and provide useful references for further reading and research.  This book aims to support software developers and engineers in realizing highly secure cloud-based applications, and also provides an introduction to the field including some relevant technical background for interested students and computer scientists.
