Cryptography Algorithms

By: Massimo Bertaccini

Overview of this book

Cryptography Algorithms is designed to help you get up and running with modern cryptography algorithms. You'll not only explore old and modern security practices but also discover practical examples of implementing them effectively. The book starts with an overview of cryptography, exploring key concepts including popular classical symmetric and asymmetric algorithms, protocol standards, and more. You'll also cover everything from building crypto codes to breaking them. In addition to this, the book will help you to understand the difference between various types of digital signatures. As you advance, you will become well-versed with the new-age cryptography algorithms and protocols such as public and private key cryptography, zero-knowledge protocols, elliptic curves, quantum cryptography, and homomorphic encryption. Finally, you'll be able to apply the knowledge you've gained with the help of practical examples and use cases. By the end of this cryptography book, you will be well-versed with modern cryptography and be able to effectively apply it to security applications.

Chapter 9: Crypto Search Engine

This chapter will discuss the technique of searching in encrypted data and provide some basic information on search engines in general and the math behind them. Then we will discover an innovative search engine that is able to work with encrypted data: the Crypto Search Engine (CSE).

This invention was projected and developed by Cryptolab, https://www.cryptolab.us/, a cybersecurity company active in data privacy and protection, founded in 2012 as a cryptography laboratory by me and my co-founders, two data science engineers, Alessandro Passerini and Tiziana Landi. The aim of Cryptolab is to give more privacy and security to the data transmitted and processed over the internet and then stored and shared in the cloud. Another website you can refer to is the web page of CSE: https://www.cryptolab.cloud/.

We are going to talk about homomorphic encryption and, in particular, homomorphic searching, which is one of the most fascinating problems I have...
