Abstract

Peer-to-peer (P2P) networks have revolutionized file sharing by allowing users to exchange data directly without relying on centralized servers. This decentralized model enhances scalability, efficiency, and resource utilization. However, it also introduces significant security challenges such as malware distribution, lack of authentication, data integrity risks, and vulnerability to unauthorized access. This paper explores the structure of P2P file sharing systems, identifies key security threats, and evaluates existing countermeasures. It also highlights the need for improved security protocols, including encryption, digital signatures, and peer trust models to ensure safer file-sharing experiences in P2P environments.
