【摘要】：随着移动互联网以及各类移动终端的广泛普及,各种面向移动设备的服务和应用如雨后春笋般出现,这其中以基于位置服务为核心服务的作用和地位都是其他各类服务所无法比拟的。除了专门应用于定位导航的软件之外,各类聊天应用、游戏应用、社交应用等目前都集成了基于位置的服务。在给用户提供更加具体化、实时化、生活化服务的同时,也提升了应用程序自身的互动性。而这一切实现的基础就是提供安全可信位置信息的无线定位技术。安全可信的位置信息对于各类基于位置服务和应用来说都是至关重要的。然而,现阶段用于提供位置信息的各类基础设施,特别是用于室内定位系统的设备在面对各类攻击时,例如信号强度攻击、信号重放攻击时,往往缺乏有效的应对手段。当针对于这些设备的攻击出现时,定位系统的准确性通常会受到严重的影响。本文首先研究了当前国内外各种针对无线定位技术提出的安全定位算法,接着从定位系统实际遇到的问题出发,借鉴其他安全定位算法的思想,以提高室内定位系统的抗干扰能力为目标,针对于定位节点(AP)最容易受到的信号强度攻击,研究了信号强度攻击对于室内定位系统的影响。并设计了两种在受到信号强度攻击时能够保证系统安全性和定位数据可信的安全定位算法。随后,基于安卓(Android)系统实现了个结合中科院计算技术研究所定位引擎接口的测试、仿真软件,利用中科院计算所的ViMap定位系统及计算所的实验环境上验证了算法的有效性。实验结果证明,通过利用所提出算法,能够显著改进定位系统在受到信号强度攻击情况下的鲁棒性和定位结果的可信性。本文的贡献在于,针对室内无线定位系统的安全可信技术进行了比较深入的研究。设计并实现了两个适用于室内无线定位系统的安全定位算法,保证定位系统在受到信号强度攻击时仍然能够给出正确的定位结果的同时能够识别和移除恶意节点。另外,利用所编写的应用程序简化了系统采样、仿真等过程,提高了定位系统工作效率
[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.
