基于数字签名的物联网感知层的安全机制研究

摘要

随着信息技术及网络通信技术的飞速发展,物联网技术蓬勃发展.在物联网环境下,不仅包含过去的网络环境组件,更加入了智能对象,因此将形成数以亿计的数据量,这些庞大的数据将造成感知层庞大的计算成本.为此,该文在感知层使用安全水平协议的概念来降低计算成本,并在中介层与感知层之间以数字签名的概念提出轻量级安全机制,通过中介层使感知层内感测节点的身份具有可验证性与不可否认性,进而提升物联网的安全性.%With the rapid development of information technology and network communication technology,the Internet of Things technology to flourish.In the Internet of Things environment,not only contains the past network environment components,but also joined the intelligent object,it will form hundreds of millions of data,these huge amount of data will result in a huge computing cost.This paper use the concept of security level protocol to reduce the cost of computing,and propose a light weight security mechanism based on the concept of digital signature between the mediation layer and the perceptual layer.Through the intermediary layer,the identity of a verifiable and non-repudiation,thereby enhancing the security of things.
