[privacy preserving DHT] Coin flipping request delegation #23
Coin Flipping Request Delegation
The goal of Coin Flipping Request Delegation (CFRD) is to add plausible deniability of routing and lookup requests in P2P networks, with special emphasis on DHT networks. The CFRD lookup protocol works by probabilistically creating a new lookup from a received routing request.
CFRD in Kademlia DHT
In a Kademlia lookup request (as defined by these specs), the lookup initiator creates an ordered shortlist containing
The CFRD construction transforms
This mechanism adds plausible deniability to DHT lookups, since (privacy) adversaries monitoring network requests (locally and to a certain threshold) will not be able to distinguish between original content lookups from lookups that were initiated because of the CFRD mechanism. This mechanism aims at decoupling peer behaviour (network request) from user behaviour (interests and personal behaviour).
