摘要
物联网技术在近年来得到了快速的发展,市场上出现了各种各样的物联网设备。其中,网关在整个物联网系统中起着举足轻重的作用,它能够连接起物联网中的各个设备。网关中保存着大量的敏感信息,而常见的信息都是以明文的方式进行传输的,作为物联网系统的核心设备,网关已经成为许多不法分子重点攻击的对象。为了解决目前市场上农业物联网系统中信息传输可靠性不强的问题,以嵌入式Linux系统为平台,将AES-128加密算法运用到网关服务器与客户端的传输环节,使得信息传输系统的安全性和保密性得到了提高。
With the rapid development of IoT technology,a variety of IoT devices are emerging.Among them,the gateway plays a pivotal role in the whole IoT system.It connects devices in the IoT.A large amount of sensitive information is stored in the gateway,the common information is transmitted in plaintext,as the core equipment of the Internet of things system,the gateway has become the focus of many criminals.In order to solve the problem of weak reliability of information transmission in agricultural IoT system in the existing market,this paper takes embedded Linux system as the platform,AES-128 encryption algorithm is applied to the transmission link between gateway server and client.The security and confidentiality of the information transmission system have been improved.
