Application Of Embedded System Base Internet Security

The embeded technology has been developed rapidly in recent years,whatever in the industry inspection or in the facilities,it makes great progress. Especially in recent two years,with the facilities been informative,intelligent and networking,the embeded system has been used more and more widely in some little facilities. When these facilities rapid their steps in internet,this system' s network security is noted by all,which brings forword a new task for the network security. In this theme,I talk about the security of embeded system. What' s more,according to the characters of embeded system,I put forword a new mechanism on its securityThere are six parts in this theme. The first part introduces the history,the actuality and the prospect of the network. At the same time,it sets forth what' s the internet appliance (IA). The second part recommends the functions of the network service,and the ways that embedded system goes into the internet. The third part makes it clear the requirement and the technology for the network security,the principle of the crytography. The forth introduces the processes of the network security for the embedded system,basing on the specialties of the embedded system and the security mechanism of Ipsec. And the fifth part of this theme presents an exampe of the embedded system by the author. In the end,I prospect the remaining problems.
