Symmetric Cryptography, Volume 1: Design and Security Proofs

Detailed Summary

Symmetric cryptography plays a crucial role in securing communications in today's digital world, protecting sensitive data from unauthorized access and ensuring privacy. This book delves into the principles, design methodologies, and security evaluation techniques of symmetric cryptosystems. It not only introduces the reader to core concepts such as block ciphers, stream ciphers, and cryptographic hash functions but also explores advanced topics like automated security proofs, side-channel resistance, and modern cryptanalysis techniques.

In Volume 1, the authors focus on building a solid foundation in understanding how symmetric cryptographic algorithms are designed. Starting from essential cryptographic concepts, the book gradually progresses to sophisticated industry-standard mechanisms like the Advanced Encryption Standard (AES) and lightweight cryptographic algorithms for constrained devices. A central theme throughout is the importance of rigorous mathematical proofs to ensure the security of cryptographic constructs, providing readers with both the tools and confidence to assess security claims effectively.

Split into logically-structured chapters, this volume aims to strike a balance between theory and application. Every section is enriched with illustrations of real-world use cases, making it accessible for both academic readers and industry professionals.
