Abstract
Online social networks (OSN) have become very popular during the last years. Every day millions of people generate and consume a huge amount information via these type of networks, which are useful to find former classmate or to improve our interaction with friends. Most popular online social networks are based on centralized servers, which are responsible for the management and storage all information. Although online social networks introduce several benefits, these networks still face many challenges such as central control, privacy or security. P2P infrastructures have emerged as an alternative platform to deploy decentralized online social networks. However, decentralized distributed systems are vulnerable to security attacks from malicious peers. In this work, we evaluate P2P infrastructures against spoofing attack. In particular, we simulate and evaluate hybrid and distributed P2P architectures.
