Detection of Sybil Attacks in Structured P2P Overlay Network

Taxonomy of Structured P2P Overlay Networks Security Attacks

The survey and classification of the different security attacks in structured peer-to-peer (P2P) overlay networks can be useful to computer system designers, programmers, administrators, and users. In this paper, we attempt to provide a taxonomy of structured P2P overlay networks security attacks. We have specially focused on the way these attacks can arise at each level of the network. Moreove...

Estimating Churn in Structured P2P Overlay Networks

Structured peer-to-peer (P2P) networks have become an important alternative to the classic client-server architecture. Participating peers can join and leave the system at arbitrary times, a process which is known as churn. Many recent studies revealed that churn is one of the main problems faced by any Distributed Hash Table (DHT). As a countermeasure most DHT protocols have to invest a signif...

An Overview of Structured P2P Overlay Networks

Limiting Sybil Attacks in Structured Peer-to-Peer Networks

Structured peer-to-peer networks are highly scalable, efficient, and reliable. These characteristics are achieved by deterministically replicating and recalling content within a widely distributed and decentralized network. One practical limitation of these networks is that they are frequently subject to Sybil attacks: malicious parties can compromise the network by generating and controlling l...

Analysis of hybrid P2P overlay network topology

Modeling peer-to-peer (P2P) networks is a challenge for P2P researchers. In this paper, we provide a detailed analysis of large-scale hybrid P2P overlay network topology, using Gnutella as a case study. First, we re-examine the power-law distributions of the Gnutella network discovered by previous researchers. Our results show that the current Gnutella network deviates from the earlier power-la...
