摘要
USB接口已逐渐成为计算机上最常用的接口之一,基于USB接口的软件加密狗相对于并口或串口的软件加密狗将具有更强的通用性。论文主要讨论基于C8051F320芯片的加密狗的设计,通过分析当前加密狗被破解的方法,设计出防跟踪分析的加密狗算法流程。
As the USB interface has becoming the most popular interface, the soft dog based on the USB interface has stronger compatibility than that based on the parallel interface or serial interface. This paper mainly discusses a method for designing soft dog based on C8051F320, analyzes the method for cracking soft dog, and then designs the arithmetic flow that can prevent to be pursued.
