Serious Cryptography, 2nd Edition: A Practical Introduction to Modern Encryption

This thoroughly revised and updated edition of the bestselling introduction to modern cryptography breaks down fundamental mathematical concepts without shying away from meaty discussions of how they work. In this practical guide, you'll gain immeasurable insight into topics like authenticated encryption, secure randomness, hash functions, block ciphers, and public-key techniques such as RSA and elliptic curve cryptography.

You'll find coverage of topics like:

• The basics of 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
• How algorithms like AES, ECDSA, Ed25519, Salsa20, and SHA-3 work
• Advanced techniques like multisignatures, threshold signing, and zero-knowledge proofs

NEW TO THIS EDITION: This second edition has been thoroughly updated to reflect the latest developments in cryptography. You'll also find a completely new chapter covering the cryptographic protocols in cryptocurrency and blockchain systems.

Whether you're a seasoned practitioner or a beginner looking to dive into the field, Serious Cryptography will demystify this often intimidating topic. You'll grow to understand modern encryption and its applications so that you can make better decisions about what to implement, when, and how.
