嵌入式系统的安全技术研究

随着嵌入式系统的网络化发展，嵌入式系统的安全将成为嵌入式系统必须考虑的问题。嵌入式系统的资源有限性使它的安全问题比一般的桌面系统更加复杂。因此，如何构建一个安全的嵌入式系统是个很值得研究的问题。同时，嵌入式系统的安全不是安全嵌入式系统的附加功能，安全嵌入式系统要在整个设计过程中考虑安全因素，从而决定采用哪种安全技术。从安全的整体性出发，研究了嵌入式系统的各种安全技术，总结归纳出几种安全增强方式，并指出其相应的应用特点，为如何建立嵌入式系统的安全提供依据。

Study of Technology of Security in Embedded System

As the development of embedded systems in the network,the problems of its security needs to be considered.The limitation of sources used in embedded systems make its secure problem more complicated than normal desktop system.So,how to build a secure embedded system need to study.On the other hand,the security of embedded system is not the additional function,but need to be considered in the whole process of design.Bases on the whole secure system,studies the various technologies of security in embedded system and points out the applying features of those technologies,thus providing some references for building a secure embedded system.
