Garlic-Routing
Routing technology as implemented in Kovri

The Basics

The term @garlic-routing has a diverse history of varying interpretations. As it currently stands, Monero defines @garlic-routing as the method in which @Kovri and @I2P create a @message-based anonymous overlay network of internet peers.

The @Garlic-Encryption of @Garlic-Routing is similar to the @Layered-Encryption of Onion Routing and effectively conceals the IP address of the sender and secures information sent from the sender to its @destination (and vice-versa).

History

In written form, the term @garlic-routing can be seen as early as June of 2000 in Roger Dingledine's Free Haven Master's thesis (Section 8.1.1) as derived from the term Onion Routing.

As recent as October of 2016, #tor-dev has offered insight into the creation of the term @garlic-routing:

Nick Mathewson:

[I think that there was some attempt to come up with a plant whose structure resembled the 'leaky-pipe' topology of tor, but I don't believe we ever settled on one.]

Roger Dingledine:

during the free haven brainstorming, there was a moment where we described a routing mechanism, and somebody said "garlic routing!", and everybody laughed. so we for sure thought we had invented the name, at the time.

Note: permission to use the aforementioned quotes were granted by Nick Mathewson and Roger Dingledine

In-depth Information

In technical terms, for @Kovri and @I2P, @garlic-routing translates to any/all of the following:

  • @Layered-Encryption (similar to the @layered-encryption in Onion Routing)
  • Bundling multiple @messages together (garlic cloves)
  • ElGamal/AES @encryption

Note: though Tor uses @layered-encryption, Tor does not use ElGamal and is not message-based.

Notes

  • In terms of Onion/Garlic Routing, another way to envision layered @encryption is by replacing the onion/garlic with a Matryoshka doll
