中文摘要: 对等资源共享应用在移动互联网中扮演着越来越重要的角色,迫切要求节点能在不安全、不可信的环境中进行有效地协作完成资源共享任务,但移动对等网络的自组织、节点移动性、弱中心化及资源受限特点为动态安全的资源共享提出了新的挑战,目前传统的集中式或分布式资源共享及其安全保障方法已无法适应新的需求。本课题以不可信网络环境中的资源共享为背景,研究无线移动网络环境中的优化覆盖问题,在此基础上设计移动覆盖网拓扑构造方法;提出高效节能的移动对等资源发现算法;针对移动对等环境下的零知识背景,利用贝叶斯博弈构建动态安全的资源请求与授权模型;之后,设计抵御数据窃取和篡改等攻击行为的网络编码方案,并将其应用到移动对等资源共享中实现节点的隐私数据保护;最终建立安全的移动对等资源共享原型系统验证所提理论的正确性和可行性。本项目致力于为移动对等资源共享提供安全保障,研究成果对促进不可信环境中动态安全的对等资源共享有重要意义。

英文摘要: Peer-to-peer (P2P) resource sharing has been playing an increasingly important role in mobile Internet, and it urgently requires that the mobile peers can effectively collaborate to complete the resource sharing under the insecure and untrusted mobile P2P environments. However, the main characteristics of the mobile P2P networks are self-organization, mobility, decentralization and resource-constrained, which poses new challenges on the dynamic and secure resource sharing strategy. And the existed secure centralized or distributed resource sharing schemes have been unable to adapt to new requirements. In this topic, we view the resource sharing for untrusted mobile P2P networks as the research background. Firstly, the optimal coverage problem in wireless mobile networks is studied, and then the mobile overlay network topology construction scheme on the basis of the physical topology is designed. After that, an energy efficient mobile P2P resource discovery algorithm is proposed. Secondly,for the zero-knowledge environments in mobile P2P netowrks, the Bayesian game theory is used to build the secure resource request and authorization model. Thirdly, we study a network coding scheme which can defend against various malicious attacks. And then the network coding scheme is used in the mobile P2P resource sharing app
