Summary:

This book provides an in-depth analysis of Signal and Messaging Layer Security (MLS) protocols, focusing on end-to-end encryption (E2EE) for secure digital communication. Authored by Rolf Oppliger, the work examines the cryptographic techniques behind the Signal protocol, such as the extended Triple Diffie-Hellman (X3DH) key exchange and double ratchet mechanisms, while addressing advanced security features like forward secrecy and post-quantum cryptography. Additionally, the book explores the scalability challenges of E2EE protocols in group messaging and introduces the MLS protocol as a solution, detailing its group member organization via binary trees for key management and access control. Targeted at readers with foundational knowledge of cryptography, this work aims to enhance understanding of the design, implementation, and integration of Signal and MLS protocols in modern secure messaging systems.
