【摘要】 目前,P2P技术广泛应用到文件共享、即时通讯等众多领域中,在这些应用获得了一定成就的同时,也给网络中的用户提供了的帮助和带来了享受。在众多应用中,文件共享的应用是P2P技术在网络中应用最多同时也是比较成功的应用之一,但是由于P2P技术是近些年来才发展起来的新技术,所以在P2P的网络应用中还有许多问题需要解决才能网络更加完善。但P2P的发展也存在一些问题,很多P2P应用基于各自的平台,相互之间缺乏交流,不能资源共享;P2P的安全性一直以来没有得到可靠的解决,极大的限制了其应用和发展。Sun公司提供的JXTA平台,它是一个理想的P2P应用平台,平台附带的安全机制可以提高建立在其上P2P的应用程序的安全性,而且该平台也是实现各种P2P软件互通的一个理想的平台。论文对现有P2P模式及应用模型进行了研究,并分析了其不足之处,同时对JXTA平台的特性,六大协议,平台提供的安全机制进行了深入的探讨。从而提出引入JXTA作为开发的理想平台,并对该模型添加了用户身份认证,信任反馈等模块。通过本论文的研究,首先通过用户身份认证,用户评价反馈来提高P2P文件共享系统的安全性;然后以JXTA为平台实现P2P文件共享系统的互通。从而最终实现了一个更安全的基于JXTA平台的P2P文件共享系统的应用模型,该模型具有用户身份认证、评价反馈、文件共享等功能。更多还原

【Abstract】 The P2P technology have wider application in file-sharing, instant messaging and many other areas now, In these applications access to certain achievements, but also to the network users with the help and bring enjoyment. Among the many applications, Application of file-sharing P2P technology is most widely used in the network is also one of the more successful applications. However, P2P technology is new technologies only developed in recent years, Therefore, the application of P2P networks there are many problems to be solved in order to improve network. But there are some problems stunting the P2P, i.e. no communications between the applications based on the P2P and they can’t share resource. Because the safety problem has not been well solved, which limits it’s application and development seriously.Sun offers the JXTA platform is an ideal application platform for P2P,Platform attached to the establishment of security mechanisms can improve in their applications on P2P security,And the platform to achieve a variety of P2P software is an ideal exchange platform.Papers on the P2P model and the application of existing models have been studied,And analysis of its deficiencies, At the same time, the characteristics of the JXTA platform, six agreements, provided platform security mechanisms of an in-depth. JXTA in order to introduce as an ideal platform for the development and added to the model of user authentication, trust, feedback modules.In this research, through the membership authentication and evaluate feedback improve the security of the P2P file sharing system firstly; then the P2P file sharing system based on JXTA platform can realize intercommunication each other. Thus realized the P2P file sharing system based on JXTA is more safer. Including the membership authentication, evaluate feedback, the file uploading and downloading function model. T更多还原
