This book provides an initial but broad view of searchable encryption research from the early 2000s to the latest results up to 2022. The authors begin with the motivation, background, and context information necessary for the main body of this book. It includes a few classic results to illustrate how searchable encryption has evolved mainly from the perspectives of security, performance and functionalities.The authors elaborate on why information leakage in searchable encryption may compromise user privacy via various leakage-abuse attacks and effective approaches to mitigate these issues. It discusses recent attempts for full-fledged encrypted database systems, and presents how to deploy searchable encryption in real-world scenarios by taking other practical considerations into account. This book also provides the descriptions of searchable encryption as comprehensive as possible with minimum rigorous analysis and formal proofs. It offers many searchable encryption topics by introducing the underlying principles and providing intuitive security and performance.This book targets senior undergraduates, graduate students and researchers, who want an initial but extensive understanding of searchable encryption and encrypted databases.  Practitioners working within this related field, who want convenient access to advancements in searchable encryption and encrypted databases will also want to purchase this book weiterlesen
