Abstract: In the digital information age, data sharing and security are important research topics, data sharing technology and information security technology have developed rapidly. The reputation incentive mechanism based on interest of nodes is important in P2P file sharing system. This mechanism can reduce the transaction risk in P2P file sharing system, improve the success rate of transaction and maintain the sound development of network. In addition, in this paper, two typical security problems (naive attack and sybil attack) are studied to minimise the damage to the network. The simulation and analysis of the success rate of resource location and transaction show that the reputation incentive mechanism is correct, feasible and effective. Furthermore, it has significant improvements in security and simplicity.
Keywords: P2P network; file sharing; data security; reputation mechanism.
