【摘要】：隨著社交網(wǎng)絡(luò)飛速的發(fā)展和普及,用戶期望能夠隨時(shí)隨地的進(jìn)行即時(shí)通信和開(kāi)展社交活動(dòng),但傳統(tǒng)網(wǎng)絡(luò)由于通信范圍的限制以及其他原因,不能夠很好的滿足用戶的這一需求。而基于MANET的普適社交網(wǎng)絡(luò)能夠彌補(bǔ)傳統(tǒng)的基于互聯(lián)網(wǎng)的社交網(wǎng)絡(luò)的不足,支持用戶隨時(shí)隨地的進(jìn)行即時(shí)通信和開(kāi)展社交活動(dòng),有著很好的發(fā)展前景。然而在用戶使用普適社交網(wǎng)絡(luò)通信的同時(shí),可能會(huì)受到不期望內(nèi)容的干擾,這些不期望內(nèi)容可能會(huì)入侵用戶設(shè)備、降低通信效率、影響用戶對(duì)移動(dòng)設(shè)備的使用體驗(yàn),甚至?xí)茐挠脩粼O(shè)備并影響用戶的正常通信。因此,控制不期望內(nèi)容來(lái)源產(chǎn)生的不期望內(nèi)容成為了普適社交網(wǎng)中至關(guān)重要的問(wèn)題。本文基于信任管理設(shè)計(jì)和實(shí)現(xiàn)了PSNController來(lái)對(duì)普適社交網(wǎng)絡(luò)中的不期望內(nèi)容進(jìn)行控制,該系統(tǒng)對(duì)流量變化率和用戶行為等方面進(jìn)行綜合分析,自動(dòng)對(duì)不期望內(nèi)容進(jìn)行識(shí)別和控制。我們通過(guò)模擬不同類(lèi)型的惡意攻擊對(duì)PSNController原型系統(tǒng)的準(zhǔn)確性,高效性和魯棒性進(jìn)行了測(cè)試。結(jié)果表明,PSNController原型系統(tǒng)能夠有效并準(zhǔn)確的識(shí)別網(wǎng)絡(luò)中的不期望內(nèi)容來(lái)源并控制不期望內(nèi)容,同時(shí)在多種惡意攻擊下,能夠抵御各類(lèi)攻擊并且準(zhǔn)確的識(shí)別并控制不期望內(nèi)容,具有很好的魯棒性。最后,我們對(duì)PSNController原型系統(tǒng)的用戶接受度進(jìn)行了調(diào)查,從測(cè)試結(jié)果可以看出,測(cè)試者對(duì)PSNController原型系統(tǒng)的易用性,有用性,用戶界面,玩賞性,直觀態(tài)度這五個(gè)方面都有著很好反饋,體現(xiàn)了PSNController原型系統(tǒng)良好的用戶接受度。本論文的主要貢獻(xiàn)如下:(1)基于課題組之前的研究結(jié)果,設(shè)計(jì)并實(shí)現(xiàn)了PSNController。(2)設(shè)計(jì)一系列的性能評(píng)估測(cè)試和不同類(lèi)型的攻擊,通過(guò)這些測(cè)試對(duì)于PSNController原型系統(tǒng)的性能進(jìn)行了評(píng)估。(3)使10位不同背景和職業(yè)的用戶同時(shí)使用PSNController,然后再進(jìn)行接受度的調(diào)查,通過(guò)設(shè)定調(diào)查問(wèn)卷,來(lái)調(diào)查PSNController有用性,用戶接受度等方面以便于考察PSNController是否有商業(yè)化潛力和良好的發(fā)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.
