With the advent of IT revolution, the volume of data produced has increased exponentially and it is still showing an upward trend. This data may be abundant and enormous but it’s a precious resource and it should be managed properly. In the management of this precious resource, cloud technology is playing an important role. Storing data over the cloud rather than on local storage has many benefits, but apart from these benefits there are some privacy concerns in storing sensitive data over third-party servers; these concerns can be addressed by storing data in an encrypted form. However, encryption solves the problem of privacy but also engenders some other serious issues which includes infeasibility of the fundamental search operation and reduction in flexibility of sharing the data with other users, amongst others. To address these issues, the concept of searchable encryption was introduced. This book provides every necessary detail required to develop the secure searchable encryption scheme using both symmetric and asymmetric cryptographic primitives along with the appropriate security models which ensures the minimum security requirements for real-world application.
