GPN23: Onion Services: Design, Protocol and Implementation
Onion Services are a crucial part of the Tor ecosystem and provide a clever way for anonymously hosting location hidden network services. Almost all of us know about them but how do they work in detail? This talk explains the technical details from .onion addresses up to the transfer of actual TCP stream data.
This talk aims to give an introduction into the design, protocol and implementation of onion services.
The idea is to give the audience an understanding of what happens internally inside the Tor network from what .onion addresses actually are over the cryptographic building blocks over to the actual messages sent over the protocol.
The audience is expected to have a basic understanding of what the idea behind Tor is, as well as a high-level overview on the cryptographic primitives.
