This practical guide to modern encryption breaks down the fundamental mathematical concepts at the heart of cryptography without shying away from meaty discussions of how they work. You’ll learn about authenticated encryption, secure randomness, hash functions, block ciphers, and public-key techniques such as RSA and elliptic curve cryptography. 

You’ll also learn: 
- Key concepts in cryptography, such as computational security, attacker models, and forward secrecy 
- The strengths and limitations of the TLS protocol behind HTTPS secure websites 

- Quantum computation and post-quantum cryptography

这本现代加密实用指南打破了密码学核心的基本数学概念，而不会回避关于它们如何工作的详细讨论。您将学习认证加密、安全随机性、哈希函数、分组密码和公钥技术，如RSA和椭圆曲线密码术。
您还将了解：
-密码学中的关键概念，如计算安全性、攻击者模型和前向保密性
-HTTPS安全网站背后TLS协议的优势和局限性
-量子计算与后量子密码
