Attacks Against Peer-to-peer Networks and Countermeasures
Peer-to-peer (P2P) networks have many distinct aspects that are different from traditional client-server networks. The most significant point is that each peer acts as both server and client roles in P2P network. In other words, there is no central server that used for storing the files and providing download. All nodes download files directly from other peers. P2P networks contain ad hoc, dece...
متن کاملLow-Resource Eclipse Attacks on Ethereum's Peer-to-Peer Network
We present eclipse attacks on Ethereum nodes that exploit the peer-to-peer network used for neighbor discovery. Our attacks can be launched using only two hosts, each with a single IP address. Our eclipse attacker monopolizes all of the victim’s incoming and outgoing connections, thus isolating the victim from the rest of its peers in the network. The attacker can then filter the victim’s view ...
متن کاملEclipse Attacks on Bitcoin's Peer-to-Peer Network
We present eclipse attacks on bitcoin’s peer-to-peer network. Our attack allows an adversary controlling a sufficient number of IP addresses to monopolize all connections to and from a victim bitcoin node. The attacker can then exploit the victim for attacks on bitcoin’s mining and consensus system, including N-confirmation double spending, selfish mining, and adversarial forks in the blockchai...
متن کاملTAC: A Topology-Aware Chord-based Peer-to-Peer Network
Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...
متن کاملPeer-to-Peer Security
Peer-to-peer networks break the dominant network paradigm of client-server relationships in information exchange by allowing heterogeneous multipurpose machines to interact and share functionality. Like any architecture, different systems have different purposes and necessitate different security protections. This chapter will identify several key features of peer-to-peer networks and the secur...
