What is Practical Cryptography?
Practical Cryptography is a book that was published in 2003 by Wiley Publishing. It is co-authored by Niels Ferguson and Bruce Schneier. The book covers various aspects of cryptography engineering, such as design principles, protocols, algorithms, implementation issues, testing, evaluation, standards, attacks, countermeasures, and case studies. The book aims to provide practical guidance for cryptography practitioners, such as developers, engineers, architects, managers, consultants, auditors, and researchers. The book assumes some basic knowledge of mathematics and computer science, but does not require advanced expertise in cryptography.
Who is Bruce Schneier?
Bruce Schneier is an internationally renowned security technologist, referred to by The Economist as a "security guru". He is the author of eight booksincluding the best sellers Beyond Fear: Thinking Sensibly about Security in an Uncertain World, Secrets and Lies,andApplied Cryptographyas well as hundreds of articles, essays, and papers on various topics related to security and cryptography. He is also the founder and chief technology officer of Counterpane Internet Security, a company that provides managed security monitoring services. He is a fellow of the Berkman Center for Internet and Society at Harvard Law School, and a board member of the Electronic Frontier Foundation. He is also a frequent speaker at conferences, events, and media outlets around the world.
Why is Practical Cryptography important?
Practical Cryptography is important because it bridges the gap between theory and practice in cryptography. It provides a comprehensive and up-to-date overview of the state-of-the-art in cryptography engineering, as well as a clear and concise explanation of the underlying concepts and principles. It also offers valuable insights and tips on how to avoid common pitfalls and mistakes, and how to design and implement secure systems that meet the requirements and expectations of users, customers, regulators, and adversaries. The book is not only useful for cryptography practitioners, but also for anyone who wants to understand how cryptography works and why it matters in today's world.
Practical Cryptography vs Applied Cryptography
As mentioned earlier, Practical Cryptography is not the only book by Bruce Schneier on cryptography. In fact, it is a sequel to his earlier book, Applied Cryptography, which was published in 1996. Applied Cryptography is also a very popular and influential book in the field of cryptography, but it has a different focus and style than Practical Cryptography. In this section, we will compare and contrast the two books and their differences.
Similarities between Practical Cryptography and Applied Cryptography
Both books are written by Bruce Schneier, who is a recognized authority and leader in cryptography and security. Both books cover a wide range of topics and aspects of cryptography, such as symmetric encryption, public-key encryption, digital signatures, hash functions, message authentication codes, key exchange protocols, random number generation, stream ciphers, block ciphers, modes of operation, padding schemes, cryptanalysis, side-channel attacks, and more. Both books also include source code in C for some of the algorithms and protocols discussed in the books. Both books are intended for readers who have some background in mathematics and computer science, but not necessarily in cryptography.
Differences between Practical Cryptography and Applied Cryptography
The main difference between the two books is that Applied Cryptography is more theoretical and descriptive, while Practical Cryptography is more practical and prescriptive. Applied Cryptography focuses more on explaining how various cryptographic algorithms and protocols work, what are their properties and limitations, and what are their applications and implications. Applied Cryptography also covers more historical and exotic cryptographic techniques, such as classical ciphers, one-time pads, knapsack schemes, zero-knowledge proofs, secret sharing schemes, quantum cryptography, etc. Applied Cryptography is often considered as a reference book or an encyclopedia of cryptography.
```html Which book should you read?
The answer to this question depends on your level of expertise and interest in cryptography. If you are a beginner or a casual reader who wants to learn the basics of cryptography and how it works, you may find Applied Cryptography more accessible and informative. If you are an intermediate or an advanced reader who wants to learn how to apply cryptography in real-world scenarios and how to design and implement secure systems, you may find Practical Cryptography more useful and relevant. Of course, you can also read both books if you want to get a comprehensive and in-depth understanding of cryptography.
