Abstract: The trusted networking of the IoTaware node is the basis for the trusted environment of the sensing environment, but there is no trusted networking mechanism suitable for the sensing node currently. Aiming at this problem, this paper proposes a trusted networking mechanism suitable for IoTaware nodes. It ensures efficient access and node networking through efficient authentication and twoway trusted authentication, which can ensure that the activation of the sensing node and the access are trusted, thus ensuring the trusted activation of the IoTaware node and the trusted sensing network. Simulation experiments show that compared with the traditional security mechanism, the trusted networking mechanism proposed in this paper is an active measurement and defense mechanism, which can effectively prevent malicious code, while low energy consumption, and does not affect the life cycle of the sensing node.

摘要： 物联网感知节点的可信组网是感知环境可信的基础，但是当前缺乏适用于感知节点的可信组网机制.针对这一问题，提出了一种适用于物联网感知节点的可信组网机制，通过接入时高效的身份验证以及双向可信鉴别机制保障接入和节点组网的可信，有效保证了感知节点的启动和接入可信，从而保障了物联网感知节点的启动可信及感知网的组网可信.仿真实验表明，与传统的安全机制对比，所提出的可信组网机制是一种主动度量和防御机制，能够有效防止恶意代码，同时能耗低，不影响感知节点的生存周期.
