【摘要】 随着嵌入式系统中的应用程序越来越多,嵌入式应用软件的盗版问题也日趋严峻.为了保护嵌入式系统中的软件版权,本文提出了一种基于CF卡U ID进行数据或软件加密保护方案,并详细给出了软件保护模型与原理,特别地介绍了W indow s CE中获取CF卡U ID的编程方法,指出了利用U ID作为密匙的优点,同时,设计了一套基于CF卡U ID的实用、高效的数据加密、解密算法.更多还原

【Abstract】 With the development of application programs in embedded system,more and more pirate softwares of the programs emerges.In order to protect the intellectual property rights(IPRS) from violations,we presented a solution to the problem: encrypting either data or seftwares based on a UID in CF card,offering a software-protecting model and its working principle in detail,especially introducing a programming method for obtaining UID from CF card under the circumstances of Windows CE,and pointing out the advantages of using UID as stream key,and creating a algorithm system for encrypting and decrypting data as well as softwares.更多还原
