摘要
随着嵌入式系统越来越广泛的应用,嵌入式系统应用系统的开发者必然面临系统被仿制或剽窃的问题。为了使更多的嵌入式系统的原创者能有效地保护自己的开发成果和知识产权,文章介绍了嵌入式系统加密芯片DM2016的结构、特点及在数字电视加密领域的应用,同时给出了BlowFish算法在嵌入式主系统中的加密方法及应用。
With more and more extensive application of the embedded system, the developer of the embedded system must face the problem that the system is copied or plagiarized. For the purpose that more original creators can protect their own development achievement and intellectual property right effectively, this paper has presented the configuration of the encrpytion chip DM2016, including its characteristic and its application in the digital television. The encrpytion technology and the method of the BlowFish algorithm in the embedded system is also given in this paper.
