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.

CSE explained

Data is often communicated across networks and stored on remote servers, which may be unsecured and non-private; eventually, it needs to be browsed, searched for, and manipulated regardless of the location where it is held. In the case of sensitive data (for example, in healthcare), it needs to be kept secure and private throughout the process. State-of-the-art technology regarding sensitive data management on remote servers achieves this objective via sub-optimal combinations: sensitive data is usually made secure by local encryption and then communicated and remotely stored. In the event of requests to browse or search, it is decrypted on the remote server and then accessed. If manipulation is requested, additional encryption may even be necessary. This combination is functional but sub-optimal as it wastes computational power and it exposes sensitive data in a clear-to-read form on remote servers (which are often provided by third-party cloud services).
