A Key Management Mechanism for DHT Networks

This paper proposes a key management mechanism by DH distributed key tree for the DHT network, which is based on the DHT network routing mechanism and network topology structure. The scheme uses the DH algorithm for key agreement, to ensure that the nodes in the DHT network are able to maintain a limited number of keys, and on this basis to complete encryption of routing messages across the network. The key management mechanism provides a secure shared key for the data encryption between the nodes in the DHT network, and maintains a high degree of consistency with the DHT network topology structure, and it has broad application prospects.
