中文摘要： 本项目以物联网应用框架为背景，研究该背景下混合式无线传感网的容忍入侵结构和容侵关键技术。本项目重点研究三个方面，首先是一种隐层支持的面向物联网的混合式传感网的容侵结构，其关键难点在于面向物联网的多基站、多类型节点的跨区域混合式网络结构，该结构区别于现存的无线传感网、无线局域网和无线ad hoc网络,因而该网络结构下的容侵的安全结构研究是新颖而且富有挑战的；其次是在该结构下挖掘移动节点在入侵检测、网络容侵能力修复方面的作用，其中移动节点跨基站、跨区域的漫游巡查，其安全接入、节点认证安全和组合安全问题是研究难点；最后，研究在恶劣环境下，节点损坏/变节对网络容侵能力的影响，其难点在于多个节点变节或者损坏对网络的影响不是单个节点影响的简单相加，网络安全及容侵能力的下降应是一类新型相继故障模型。本项目的可行性在前期研究工作中得到了验证，而相关领域的研究进展也为下一步研究的技术可行性提供了支持。

英文摘要： The project researches intrusion-tolerant architecture and key technologies for the hybrid wireless sensor networks, which are based on the typical framework of Internet of Things. The emphasis of this project lies in three aspects. First, intrusion-tolerant architecture of hybrid sensor networks is supported by undisplayed layers of transmitting sub-network and data processing center. The difficult problem concentrates on interregional hybrid network architecture regarding the Internet of things. This network has multi base station and multi type node. Its architecture is different from existed wireless sensor networks, wireless local area network and wireless ad hoc network. Second, the ability in intrusion detection and tolerance recovery should be explored. Secure access, node authentication and composable security are difficult concerns especially mobile nodes roaming across different base stations and regions. Last, compromised or destroyed node will affect network tolerance capacity under circumstances of hostile environment. The problem is that the effect on network caused by multiple compromised or destroyed nodes is not added by the influence of each node. A novel complex network model of cascading failure should be presented to describe the phenomenon of the dropping of network security and tolerance
