加密方法在射频RFID系统中的应用

在21世纪人类将要在基于互联网技术的前提上,实现物品相连接的网络,而这种网络就称之为物联网。物联网通过无线识别RFID(Radio frequency identification,RFID)将物品与信息网络相联通,利用Internet达到各种物品信息的综合集成,构成多种信息综合的"Intemet of things"。RFID技术实现后,最重要的因素就是安全,本文通过对物联网系统的分析,以及信息加密方式的分析,对通用的DES和AES加密方式进行分析的同时,提出一种混沌加密方式,从而设计出一种更为安全的加密形式,可以使系统变得更为完善。

Application of encryption in RFID system

In the 21~(st) century,basing on the Internet,we have builded a net by connecting with many different things.so we name it "Internet of things".This net send the informations of many things to the Internet by RFID(Radio frequency identification),so the Internet have the ability to better integrate the information.The technology has come true,hower,the safety of this system is the most significant to so many user.As a result,this paper focus on this field,by analyzing some encryption methods,for instance,the DES,the AES,and constrastting the sevral ways to a new method,In the end,we put forward a more security "Chaos encryption",by using this way,the safety will be better,in furthermore,this system will get more application.
