This book presents the current state of the literature on the fields of homomorphic and searchable encryption, from both theoretical and practical points of view. Homomorphic and searchable encryption are still relatively novel and rapidly evolving areas and face practical constraints in the contexts of large-scale cloud computing and big data.Both encryption methods can be quantum-resistant if they use the right mathematical techniques. In fact, many fully homomorphic encryption schemes already use quantum-resistant techniques, such as lattices or characteristics of polynomials ¿ which is what motivated the authors to present them in detail.On the one hand, the book highlights the characteristics of each type of encryption, including methods, security elements, security requirements, and the main types of attacks that can occur. On the other, it includes practical cases and addresses aspects like performance, limitations, etc. As cloud computing andbig data already represent the future in terms of storing, managing, analyzing, and processing data, these processes need to be made as secure as possible, and homomorphic and searchable encryption hold huge potential to secure both the data involved and the processes through which it passes.This book is intended for graduates, professionals and researchers alike. Homomorphic and searchable encryption involve advanced mathematical techniques; accordingly, readers should have a basic background in number theory, abstract algebra, lattice theory, and polynomial algebra.

Utilize this comprehensive, yet practical, overview of modern cryptography and cryptanalysis to improve performance. Learn by example with source code in C# and .NET, and come away with an understanding of public key encryption systems and challenging cryptography mechanisms such as lattice-based cryptography.Modern cryptography is the lifeboat of a secure infrastructure. From global economies and governments, to meeting everyday consumer needs, cryptography is ubiquitous, and used in search, design, data, artificial intelligence, and other fields of information technology and communications. Its complexity can lead to misconfiguration, misuse, and misconceptions. For developers who are involved in designing and implementing cryptographic operations in their applications, understanding the implications of the algorithms, modes, and other parameters is vital. Pro Cryptography and Cryptanalysis is for the reader who has a professional need or personal interest in developing cryptography algorithms and security schemes using C# and .NET. You will learn how to implement advanced cryptographic algorithms (such as Elliptic Curve Cryptography Algorithms, Lattice-based Cryptography, Searchable Encryption, Homomorphic Encryption), and come away with a solid understanding of the internal cryptographic mechanisms, and common ways in which the algorithms are correctly implemented in real practice. With the new era of quantum computing, this book serves as a stepping stone to quantum cryptography, finding useful connections between current cryptographic concepts and quantum related topics.
