【摘要】：随着社交网络飞速的发展和普及,用户期望能够随时随地的进行即时通信和开展社交活动,但传统网络由于通信范围的限制以及其他原因,不能够很好的满足用户的这一需求。而基于MANET的普适社交网络能够弥补传统的基于互联网的社交网络的不足,支持用户随时随地的进行即时通信和开展社交活动,有着很好的发展前景。然而在用户使用普适社交网络通信的同时,可能会受到不期望内容的干扰,这些不期望内容可能会入侵用户设备、降低通信效率、影响用户对移动设备的使用体验,甚至会破坏用户设备并影响用户的正常通信。因此,控制不期望内容来源产生的不期望内容成为了普适社交网中至关重要的问题。本文基于信任管理设计和实现了PSNController来对普适社交网络中的不期望内容进行控制,该系统对流量变化率和用户行为等方面进行综合分析,自动对不期望内容进行识别和控制。我们通过模拟不同类型的恶意攻击对PSNController原型系统的准确性,高效性和鲁棒性进行了测试。结果表明,PSNController原型系统能够有效并准确的识别网络中的不期望内容来源并控制不期望内容,同时在多种恶意攻击下,能够抵御各类攻击并且准确的识别并控制不期望内容,具有很好的鲁棒性。最后,我们对PSNController原型系统的用户接受度进行了调查,从测试结果可以看出,测试者对PSNController原型系统的易用性,有用性,用户界面,玩赏性,直观态度这五个方面都有着很好反馈,体现了PSNController原型系统良好的用户接受度。本论文的主要贡献如下:(1)基于课题组之前的研究结果,设计并实现了PSNController。(2)设计一系列的性能评估测试和不同类型的攻击,通过这些测试对于PSNController原型系统的性能进行了评估。(3)使10位不同背景和职业的用户同时使用PSNController,然后再进行接受度的调查,通过设定调查问卷,来调查PSNController有用性,用户接受度等方面以便于考察PSNController是否有商业化潜力和良好的发展前景。
[Abstract]:With the rapid development and popularity of social networks, users expect to be able to conduct instant messaging and social activities anytime, anywhere, but traditional networks are limited by the scope of communication and other reasons. MANET-based pervasive social networks can make up for the shortcomings of traditional internet-based social networks and support instant messaging and social activities anytime and anywhere. There are good prospects. However, while users are communicating with pervasive social networks, they may be disturbed by unwanted content that may intrude into user devices and reduce communication efficiency. Affect the user's experience of mobile devices, even destroy the user's device and affect the user's normal communication. Controlling the unwanted content generated by the undesired content source has become a critical issue in the pervasive social network. This paper designs and implements PSNController to control the unwanted content in the pervasive social network based on the trust management design and implementation. The system synthetically analyzes the traffic change rate and user behavior, and automatically recognizes and controls the unwanted content. We simulate the accuracy of different types of malicious attacks on the PSNController prototype system. The results show that the PSN Controller prototype system can effectively and accurately identify the source of unwanted content in the network and control the unwanted content, and at the same time, under various malicious attacks, It is robust to resist all kinds of attacks and accurately identify and control unwanted content. Finally, we investigate the user acceptance of PSNController prototype system, and we can see from the test results, The testers have good feedback on the usability, usefulness, user interface, playfulness and intuitive attitude of the PSNController prototype system. The main contributions of this thesis are as follows: 1) based on the previous research results of the research group, a series of performance evaluation tests and different types of attacks are designed and implemented. Through these tests, the performance of the PSNController prototype system was evaluated. 3) 10 users from different backgrounds and occupations were asked to use the PSN Controller at the same time, and then an acceptance survey was conducted to investigate the usefulness of the PSNController by setting up a questionnaire. In order to investigate whether PSNController has commercial potential and good development prospects.
