基于DS2432和FPGA的IFF加密方法

IFF Copy Protection Based On DS2432 and FPGA

本文主要论述了一种高级别的、针对FPGA的、基于IFF概念的加密方法。该方法利用SHA算法,通过配置FPGA内部的数据加密内核,进行与DS2432的指令问答完成身份验证过程。在目前的大多数数字系统中,这种方法可有效地防止软硬件的非法拷贝,具有很高的安全性。

A higher level, for FPGA, based on IFF concept encryption technology is discussed in this paper. Using the Secure Hash Algorithm （SHA- 1）, through the data configuration of FPGA and communication with the secure EEPROM, a Identification Friend or Foe is completed. In most of digital system design ,this method has the highest level of security. Master and exert this method has a great signification against unauthorized cloning of FPGA devices and to protect FPGA intellectual property.
