摘要
为防止MCS-51单片机应用系统被未经授权的仿造,可以通过改变系统的硬件电路及软件程序对单片机应用系统加密。本文在以Intel公司的MCS-51系列单片机为例来介绍单片机应用系统的通用加密技术基础上,分析了其优缺点,并提出一种硬件结合软件、虚实地址相互变换的综合实时加密技术可重构加密技术,以实现单片机应用系统的软硬件综合加密。
It is able to encrypt the applications system to keep from the unauthorized reproduction of MCS - 51 single chip microcomputer. This text describes the all - purpose encryption of MCS - 51 single chip microcomputer ( Intel corp. ) and analyses the encryption's merit and demerit. At the same time, This paper states a new encryption the reconfigurable encryption to actualize the integrated encryption techniques.
