Introduction to Cryptographic Definitions: A Step-By-Step Guide for Beginners - Paperback

by Fuchun Guo (Author), Willy Susilo (Author), Khoa Nguyen (Author)

Cryptographic definitions are often abstract and complex, making them challenging for beginners to understand and apply.

This concise textbook/resource provides a structured introduction to cryptographic definitions, explaining the syntax definitions and security definitions of cryptographic primitives. It builds foundational knowledge by covering essential mathematical concepts and formal definitions in cryptology. Through a carefully designed learning curve, readers will grasp key elements, why they are defined this way, and how new definitions are developed. The book's presentation enables readers to validate and propose cryptographic definitions, offering a step-by-step guide to understanding them. Topics and features: - Covers all essential components of cryptographic definitions from sets and functions, making the subject accessible to beginners - Introduces intermediate concepts to smooth the transition from basic principles to formal definitions - Equips readers with the skills to validate and propose cryptographic definitions, linking theory with research - Minimizes unnecessary complexity while retaining depth, thereby ensuring a smooth learning experience

Advanced undergraduate students, security engineers, and professionals interested in the formal foundations of cryptographic definitions will find the work an invaluable guide. The text is also an ideal reference for graduate students and early-stage researchers in cryptology and computer security.
