## The Kademlia node discovery protocol
Kademlia (KAD) is a distributed hash table (DHT) technology based on the “exclusive OR” (XOR) distance algorithm. We want to implement a more secure S/KAD extension in KAD through a secure Node ID allocation mechanism. We also monitor non-intersecting paths to help prevent attacks.
