Modern cryptography : applied mathematics for encryption and information security

Detailed Summary of the Book

This book delves deep into the fundamental principles of modern cryptography while making the subject approachable to readers of all skill levels. It begins with an essential grounding in mathematical concepts such as number theory, modular arithmetic, and probability — the bedrock of cryptographic systems. From there, the book transitions into practical cryptographic techniques, explaining key concepts like symmetric encryption, public-key cryptography, and hashing algorithms.

The beauty of this text lies in its ability to connect abstract theories with real-world applications. For example, it sheds light on how RSA, AES, and ECC (Elliptic Curve Cryptography) operate internally, and it dives into advanced topics like post-quantum cryptography and blockchain security. With a practical touch, the book also discusses cryptographic protocols used in VPNs, secure messaging, and digital signatures.

Each chapter is structured to build upon the last, offering detailed explanations, algorithm breakdowns, and illustrative examples. Exercises at the end of each section encourage the reader to apply their newly gained knowledge and solidify their understanding of cryptographic techniques.

Key Takeaways

• Master essential mathematical foundations like modular arithmetic, linear algebra, and probability, which underpin cryptographic algorithms.
• Understand key cryptographic systems, including symmetric and asymmetric encryption.
• Learn advanced techniques like elliptic curve cryptography, quantum-resilient encryption, and blockchain cryptography.
• Gain practical knowledge of modern protocols such as digital certificates, TLS/SSL, and secure email encryption systems.
