摘要：文章提出了一种云计算环境下抗欺诈行为的P2P文件共享系统激励机制——FPIM。

该激坳机制基于一级密封价格拍卖理论，云用户根据其自身资源状态、所拥有的虚拟货币量以及

文件资源属性对本次文件资源共享服务进行估价，然后根据估价与博弈策略给出相应报价，通过

博弈分析给出了 F P IM激坳机制的纳什均衡解。为了抑制恶意云用户的欺诈行为，F P IM在竞拍过

程中引入了哈希函数等安全机制来判断恶意的欺诈行为，并排除其对竞拍过程公平性的影响。分

析与实验结果表明该激励机制能够调动理性云用户积极参与文件资源共享合作的积极性，提高云

计算环境下P2P文件共享的合作成功率与能量使用效益，优化系统的整体性能。

Abstract: This paper proposes an incentive mechanism (FPIM) with resisting fraudulent conduct in mobile P2P file sharing system based on the theory of first-price sealed auction. In this incentive

mechanism, the node calculates the evaluation of a file resource sharing senace based on the resource

state, virtual currency of it and the property of file resource, then gives the corresponding price

according to the evaluation and game strategy. Through the game analysis, the Nash equilibrium

solution of FPIM incentive mechanism is given. In order to suppress the fraudulent conduct of

malicious node, FPIM introduces hash function and other securit}^ mechanisms to judge the fraudulent

conduct of node, and eliminates the impact of malicious nodes on the fairness of the auction process.

Analysis and simulation show that this incentive mechanism is able to make rational mobile nodes

activety participate in file resource sharing cooperation to maximize their own interests, improve

the success rate of file resource sharing cooperation in the whole system, reduce the system's energy

consumption，and improve title overall effectiveness of the system.

Key words: cloud computing; P2P file sharing; virtual currency; fraudulent conduct
