摘要
随着计算机技术的发展,基于单片机的软件狗成为目前的主流。USB以其特有的打包方法、编码格式、结构特性取代了以往的并口软件狗。据此设计了一种USB软件狗,给出了相应的软件和硬件设计,重点介绍其加密原理,并对其安全性进行分析。
With the development of computer technology, the soft dog based on single chip becomes the mainstream. USB replaces soft dog with the parallel port because of its packing methods, coding format and structural characters. This article introduces a new USB soft dog, including its hardware and software design, and then analyses its safety.
