Analysis on Security Issues for Mobile P2P Networks

摘要

With the development of wireless access technology and mobile computing, mobile P2P networks are supposed to thrive in file-sharing, streaming media, electronic commerce and other applications. However, due to the concepts of decentralization and multi-hop transmission, mobile P2P networks are suffering from attacks launched by malicious members. Aiming at guarding MP2P networks, this paper analyzes the challenges and attacks for MP2P networks, and gives possible countermeasures to defend the threats. Also, current reputation systems are discussed in detail, including potential threats they are facing with and so on. Furthermore, considerations on how to construct robust reputation systems are given.
