中文摘要： 密钥管理是解决物联网数据安全和隐私保护等问题的重要基础，是保障物联网信息安全的核心技术之一。物联网具有明显的异构特性，同一物联网业务的感知层节点种类和接入形式多样，网络层融合多种网络形式。这就要求物联网中的密钥管理系统能够同时满足不同类型或计算能力的感知节点间的密钥建立需求，能够满足终端节点在不同网络间切换的需求或不同网络下节点间安全通信的需求。本课题将围绕以上问题，深入、系统地研究物联网密钥管理中的跨多个网络的密钥管理问题。具体地，本课题拟研究物联网感知层的密钥管理问题，构建感知层密钥管理方案的敌手模型，利用椭圆曲线密码体制、哈希运算、异或运算等密码学工具设计与感知层异构特性相适应的轻量级(高效)密钥管理方案；研究不同网络覆盖范围内的物联网终端之间通信时和终端在不同网络间移动时面临的安全问题，设计跨多个网络的密钥建立方案。

英文摘要： Key Management is the foundation of data and privacy protection and is one of the core technologies of the information security for the Internet of Things. The Internet of Things possesses the heterogeneous characteristics obviously. There are many types of nodes and a variety of access in the perception layer, and a variety of networks in the network layer in the same business for the Internet of Things. So, a key management system should establish keys among the nodes with different types or different computing power in the perception layer. At the same time, a key management system should ensure security of the communications among the terminals switching between different networks or that among the nodes in different networks. To solve the above problems, we will research cross-multiple-networks key management for the Internet of Things in depth and systematically. In detail, we will research the key management, and build the security model for key management schemes in the perception layer. We will design the key management schemes in the perception layer with cryptographical tools, such as ellipse curve cryptology, hash fuction, XOR, and so on, which should be compatible with the heterogeneous characteristics of the perception layer. We will analyze the security issues when terminals switch between differ
