    Abstract: Performing an in-depth study on the Power Internet of Things (IoT), it is known that the distribution network faces higher security risks due to a large number of terminals, various types of equipment, and the flexible access of each device to the distribution network structure and dynamic boundary. Therefore, it is urgent to make significant research on the security control mechanism for the power distribution Internet of Things, to realize the safe access of IoT devices in the Power IoT. Firstly, this paper analyses the shortage of power system security under the background of the IoT. Secondly, trusted computing technology is represented by the TrustZone and is deeply studied, and the feasibility of its application for the security of power distribution IoT is analyzed. Furthermore, the TrustZone-based security management and control architecture for power distribution novel IoT equipment is proposed, and its integrity measurement and trusted network connection process are analyzed. Finally, the security of this architecture is analyzed briefly.

    Abstract: As the main component of indoor positioning technology, UWB technology plays an important role in promoting the development of indoor and outdoor seamless positioning technology. This paper presents a proposed localization system of a propagation channel measurement campaign performed in a smart warehouse environment whose dimension is 100 meters * 100 meters and provides an extensive model for this environment. Three different arrangements of basestations are simulated to analyze the effects of basestation constellations and virtual racks are set up to determine the approximate line-of-sight (LOS) probability. At the same time, by considering the influences of varying transmit power, using weighting and using two-way ranging, the distribution of errors and the reliability threshold are drawn and the required bandwidths are determined. Finally, according to the simulation results, the optimal layout and modulation parameters are recommended, and improvements in channel models and algorithms for future work are concluded.

    Abstract: The new round of energy reform is marked by large-scale development and utilization of new energy and re-electrification as the fundamental path, to cope with the pressure of absorbing renewable energy and stupendous access to variable loads such as electric vehicle charging piles creates several problems such as a large number of equipment failure and low standardization in the distribution network, to overcome this, the distribution Internet of Things (D-IoT) came into existence. In this paper an equivalent architecture of blockchain and D-IoT is built based on master-slave multi-chain. The combined equivalent architecture proposes the crucial application of blockchain technologies as consensus mechanism and smart contract in the D-IoT in order to explore the broad application prospects of blockchain in the D-IoT.
