微机化仪器的软硬件加密方法

The encryption methods for software and hardware of the computerized instrument

以防止微机化仪器被同行业竞争者非法仿制为目的 ,以使用 5 1系列单片机为例 ,分别介绍了几种软件及硬件的加密方法 ,采用这些方法能够使仿制者无法轻易反汇编出源程序和做硬件拷贝 ,从而保证微机化仪器不易被仿制 。

In order to prevent the computerized instrument from being modelled on by the competitors of the same trade, several encryption methods for software and hardware are introduced by taking the use of 51 series single chip processor for instance. This method can prevent the copyer from antiassembling source program and making the hardware copy easily, thus it can guarantee against the copy of the computerized instrument and realize the aim of self protection of the knowledge property right.
