Abstract

Distributed Hash Table (DHT) peer-to-peer (P2P) overlay networks have gained attention in the literature due to their characteristics such as high availability, scalability, among others. The popular implementation is the OpenDHT project, however, it does not handle the authentication of message neither nodes. Thus, it is susceptible to several attacks, including Sybil attack. In this way, the respective work aims to fill this gap through a Public Key Infrastructure. Scyther tool demonstrates the security of proposal against well-known attacks, and practical tests indicate success of implementation.

Keywords: Distributed Hash Table, Authentiation, P2P
