摘　　要：随着物联网和云计算技术的飞速发展和广泛应用,物联网搜索引擎应运而生。然而,物联网搜索引擎的开放性,使在互联网搜索领域就已经存在的数据隐私问题变得更加突出。首先,阐述了物联网搜索数据隐私保护的研究背景和安全挑战,并针对安全挑战,将密文搜索和基于属性的访问控制算法有机结合。然后,提出了基于细粒度授权的物联网搜索数据隐私保护方案,并对方案进行了安全分析和性能分析。最后,总结并指出了未来研究工作方向。With the rapid development of the Internet of things （loT） technology and cloud computing technology, the search engine for Internet of things become a hot research topic. However, because of the openness of the search of 10T, the privacy in traditional Internet search area becomes more prominent and faces more challenges. Firstly, the research background and challenges of data privacy preservation for search of loT were described. Secondly, the scheme of data privacy preservation for the search of Internet of things based on fine-grained authorization was pro- posed, which combined the encrypted search algorithm with the attribute based access control algorithm. Thirdly, the security analysis and performance analysis of the scheme were also carried out. Finally, the future research work was summarized and pointed out.
