Modern Cryptography Volume 2: A Classical Introduction to Informational and Mathematical Principle

Zhiyong Zheng, Kun Tian, Fengxia Liu

This open access book covers the most cutting-edge and hot research topics and fields of post-quantum cryptography. The main purpose of this book is to focus on the computational complexity theory of lattice ciphers, especially the reduction principle of Ajtai, in order to fill the gap that post-quantum ciphers focus on the implementation of encryption and decryption algorithms, but the theoretical proof is insufficient. In Chapter 3, Chapter 4, and Chapter 6, the author introduces the theory and technology of LWE distribution, LWE ciphers, and homomorphic encryption in detail. When using random analysis tools, there is a problem of "ambiguity" in both definition and algorithm. The greatest feature of this book is its use of probability distribution to carry out rigorous mathematical definitions and mathematical demonstrations for various unclear or imprecise expressions, so as to make it a rigorous theoretical system for classroom teaching and dissemination. Chapters 5 and 7 further expand and improve the theory of cyclic lattices, ideal lattices, and generalized NTRU cryptography.

This book is used as a professional book for graduate students majoring in mathematics and cryptography, as well as a reference book for scientific and technological personnel engaged in cryptography research.
