This conference talk from the 38th Chaos Communication Congress (38C3) introduces Reticulum, a cryptography-based networking stack designed for building sovereign communication networks that operate even in adverse conditions with high latency and extremely low bandwidth. Discover how Reticulum enables the creation of networks without surveillance, censorship, or control by eliminating source addresses, decentralizing address space control, and ensuring end-to-end connectivity with strong encryption by default. Learn about its unique features including self-sovereign portable addresses, ephemeral encryption keys with forward secrecy, and the inability to establish unencrypted links or send unencrypted packets. The presentation demonstrates how Reticulum empowers individuals to build resilient, independent networks that can interoperate freely while maintaining privacy and security, making it a tool for "Networks for Human Beings."
