随着物联网的应用普及,其信息共享的数据和用户的行为关系密切,因而物联网信息的感知性和敏感性对其信息共享的安全隐私保护要求越来越高。本文基于扩展泛化的K-匿名模型,进行了物联网的安全隐私建模,设计了一个具有良好的安全隐私保护的物联网共享平台,对其框架和设计要素进行了详细的分析。 With the popularization of the application of Internet of Things, the data of information sharing is closely related to the behavior of users, and thus the perception and sensitivity of Internet of Things information require more and more protection for the security and privacy of information sharing. Based on the extended generalized K-anonymity model, this paper constructs a IoT security privacy model and designs a IoT sharing platform with good security privacy protection. The framework and design elements are analyzed in detail.
