【摘要】：隨著移動互聯(lián)網以及各類移動終端的廣泛普及,各種面向移動設備的服務和應用如雨后春筍般出現,這其中以基于位置服務為核心服務的作用和地位都是其他各類服務所無法比擬的。除了專門應用于定位導航的軟件之外,各類聊天應用、游戲應用、社交應用等目前都集成了基于位置的服務。在給用戶提供更加具體化、實時化、生活化服務的同時,也提升了應用程序自身的互動性。而這一切實現的基礎就是提供安全可信位置信息的無線定位技術。 安全可信的位置信息對于各類基于位置服務和應用來說都是至關重要的。然而,現階段用于提供位置信息的各類基礎設施,特別是用于室內定位系統(tǒng)的設備在面對各類攻擊時,例如信號強度攻擊、信號重放攻擊時,往往缺乏有效的應對手段。當針對于這些設備的攻擊出現時,定位系統(tǒng)的準確性通常會受到嚴重的影響。本文首先研究了當前國內外各種針對無線定位技術提出的安全定位算法,接著從定位系統(tǒng)實際遇到的問題出發(fā),借鑒其他安全定位算法的思想,以提高室內定位系統(tǒng)的抗干擾能力為目標,針對于定位節(jié)點(AP)最容易受到的信號強度攻擊,研究了信號強度攻擊對于室內定位系統(tǒng)的影響。并設計了兩種在受到信號強度攻擊時能夠保證系統(tǒng)安全性和定位數據可信的安全定位算法。隨后,基于安卓(Android)系統(tǒng)實現了個結合中科院計算技術研究所定位引擎接口的測試、仿真軟件,利用中科院計算所的ViMap定位系統(tǒng)及計算所的實驗環(huán)境上驗證了算法的有效性。實驗結果證明,通過利用所提出算法,能夠顯著改進定位系統(tǒng)在受到信號強度攻擊情況下的魯棒性和定位結果的可信性。 本文的貢獻在于,針對室內無線定位系統(tǒng)的安全可信技術進行了比較深入的研究。設計并實現了兩個適用于室內無線定位系統(tǒng)的安全定位算法,保證定位系統(tǒng)在受到信號強度攻擊時仍然能夠給出正確的定位結果的同時能夠識別和移除惡意節(jié)點。另外,利用所編寫的應用程序簡化了系統(tǒng)采樣、仿真等過程,提高了定位系統(tǒng)工作效率
[Abstract]:With the wide spread of mobile Internet and all kinds of mobile terminals, a variety of services and applications for mobile devices are springing up. The role and status of location-based services are incomparable to other types of services. In addition to the application of location navigation software, all kinds of chat applications, game applications. Social applications and so on are integrated with location-based services at the same time to provide users with more concrete, real-time, and life-oriented services. It also enhances the interactivity of the application itself, which is based on the wireless location technology that provides secure and trusted location information. Secure and trusted location information is essential for all kinds of location-based services and applications. However, at this stage, all kinds of infrastructure are used to provide location information. Especially when the equipment used in indoor positioning system is faced with various kinds of attacks such as signal intensity attack and signal playback attack there is often a lack of effective response when the attack against these devices occurs. The accuracy of the positioning system is usually seriously affected. Firstly, this paper studies all kinds of secure localization algorithms for wireless positioning technology at home and abroad, and then starts from the actual problems encountered in the positioning system. Referring to the idea of other security positioning algorithms, aiming at improving the anti-jamming ability of indoor positioning system, aiming at the most vulnerable signal intensity attack to the location node APs. This paper studies the effect of signal intensity attack on indoor positioning system, and designs two secure localization algorithms which can guarantee the system security and the location data credibility when the signal intensity attacks. Based on Android (Android) system, a test and simulation software for the positioning engine interface of the Institute of Computing Technology of the Chinese Academy of Sciences (CAS) is implemented. The effectiveness of the algorithm is verified by using the ViMap positioning system of the Institute of Computing of the Chinese Academy of Sciences and the experimental environment of the Institute of Computing. The experimental results show that the proposed algorithm is used. It can significantly improve the robustness of the localization system and the credibility of the localization results under the attack of signal intensity. The contribution of this paper is that the security and trusted technology of indoor wireless positioning system is deeply studied, and two secure location algorithms are designed and implemented for indoor wireless positioning system. Ensure that the location system can still give the correct location results while recognizing and removing malicious nodes. In addition, the system sampling is simplified by using the written application program. The working efficiency of the positioning system is improved by simulation and other processes.
