45696 物联网是一个多网异构融合网络，其感知层常面临各类安全威胁。 The Internet of things (IoT) is a multiple heterogeneous network, and its perception layer is often faced with various security threats.
45697 物联网网关作为感知层和网络层的桥梁，应当具备安全管理功能，防止安全问题向上层扩散。 As the bridge between the perception layer and the network layer, the IoT gateway should have the security management function to prevent the security issue from spreading to the upper layer.
45698 针对物联网网关目前安全方面的不足，以物联网网关中间件技术为平台，设计一个通用的物联网网关安全系统。 According to the current security deficiencies in IoT gateway, a universal IoT gateway security system was proposed based on the loT gateway middleware technology.
45699 该系统可以嵌入不同的安全协议或算法，然后进行建模与分析，能够辅助安全网关的设计和具体实现。 Various security protocols or algorithms can be embedded in IoT gateway security system, and the modeling and analysis can help the design and implementation of IoT gateway.
45700 利用时间自动机对系统进行形式化建模与验证， The formal modeling and verification of the IoT gateway security system was performed by timed automata.
45701 验证结果表明物联网网关安全系统满足机密性、可用性、真实性、顽健性、完整性和新鲜性 6 项安全需求。 The results show that the loT gateway security system satisfies the security properties of confidentiality, availability, authenticity, robustness,integrity and freshness.
45702 移动低占空比无线传感器网络是近年来出现的新型网络。 Mobile low-duty-cycle wireless sensor network (MLDC-WSN) are a kind of new ad hoc networks that are appeared in recent years.
45703 在移动低占空比无线传感器网络中，由于节点的存储空间有限， In MLDC-WSN, the nodes only have limited storage spaces.
45704 并且节点的移动及睡眠会导致网络不连通、数据无法及时传输等问题，使数据很难被快速分发并存储，数据持续性较低。 Moreover, the nodes would move or sleep from time to time. Therefore, these networks have some problems such as connectivity is hard to be maintained and data are hard to be transmitted to their destinations for storage in time. As a result, data persistence (i.e., the probability that all data can be recovered after some nodes die in the networks) is low.
45705 为此，提出一种卢比变换码的分布式数据存储（LT-MDS, Luby transform codes based mobile distributed storage）算法， A distributed algorithm named LT-MDS for improving data persistence in MLDC-WSN was proposed.
