    Survey of Ubiquitous Computing Security

    • 摘要: 随着人机物互联融合的泛在计算及其关键技术的快速发展,泛在计算已成为我国智能软硬件创新研发和生态构建的研究热点,驱动了智慧家庭、工业互联网、自动驾驶、智能云计算等众多典型应用产业日益普及繁荣,其安全问题也受到越来越多研究者的关注.目前,泛在计算安全研究尚在起步阶段,相关研究成果还不能系统地解决泛在计算发展中面临的安全问题.首先对当前泛在计算及其操作系统的发展现状进行了介绍,系统阐述了泛在计算的操作系统架构.归纳和分析了近几年国内外相关研究文献,将泛在计算安全问题划分为3个层面:系统软件安全、智能设备安全和通信安全,并系统总结了各个层面的安全问题与研究现状和重点.集中分析并讨论了泛在计算4个典型应用场景(智慧家庭、工业互联网、自动驾驶和智能云计算)中特定场景相关的安全问题和研究进展.归纳总结了现有研究工作中存在的不足与问题,并指出了泛在计算安全研究面临的八大安全技术挑战与机遇.最后,通过详尽分析这些安全技术挑战,指出了泛在计算安全的8个未来研究方向.

       

      Abstract: With the development of ubiquitous computing technology and ubiquitous operating system (UOS), ubiquitous computing has become a hot research topic both in industry and academy. As classic ubiquitous computing scenarios, smart home, industrial Internet of things, self-driving, and cloud computing, have become increasingly prosperous, and their security issues have attracted the attention of researchers. Currently, as the related research on ubiquitous computing security is in its initial stage, there is still no general security methods that can solve the emerging security issues of ubiquitous computing. In this paper, we firstly review the current status of ubiquitous computing, UOS, and summarize its architecture. Then, we analyze and summarize the state-of-the-art research effort on ubiquitous computing security, and divide security issues into three major aspects: system security, device security and communication security. We discuss the security issues and related research effort in four classic ubiquitous computing scenarios. Through in-depth analysis of the shortcomings of existing research and the causes of security problem, we summarize eight key technical challenges and opportunities in ubiquitous computing security. Finally, we discuss every challenge, and point out the potential security research directions of ubiquitous computing in future.
