With the advent of the IT revolution, the volume of data produced has increased exponentially and is still showing an upward trend. This data may be abundant and enormous, but it's a precious resource and should be managed properly. Cloud technology plays an important role in data management.

Storing data in the cloud rather than on local storage has many benefits, but apart from these benefits, there are privacy concerns in storing sensitive data over third-party servers. These concerns can be addressed by storing data in an encrypted form; however, while encryption solves the problem of privacy, it engenders other serious issues, including the infeasibility of the fundamental search operation and a reduction in flexibility when sharing data with other users, amongst others.

The concept of searchable encryption addresses these issues. This book provides every necessary detail required to develop a secure, searchable encryption scheme using both symmetric and asymmetric cryptographic primitives along with the appropriate security models to ensure the minimum security requirements for real-world applications.

Chapter 1

Introduction to number theory and abstract algebra

NUMBER THEORY AND ABSTRACT ALGEBRA plays an important role in the development of cryptosystems. Their basic knowledge acts as a key ingredient to the fields like cryptography and coding theory. Therefore, in this chapter, we will give a detailed overview of these basic concepts to build a strong foundation before diving deep into the field of searchable encryption and data management. This chapter is divided two parts, the first part covers the concepts related to number theory and the second part covers the basic concepts of abstract algebra.

1.1 NUMBER THEORY

Number theory is an interesting facet of mathematics that has attracted everyone from professional mathematicians to amateurs with its captivating concepts. Number theory concepts and theorems are natural and make sense even to a layman. However, proving them essentially requires both the basic knowledge and strong background we expect from a graduate in Computer Engineering. In this section, we will cover all the necessary concepts of number theory needed for the de...
