| 摘 要： | 介绍了一种应用DS2432器件实现双向认证及软件功能保护的方法。先分析了信息认证的基本计算模型,然后设计了一种应用DS2432器件并使用国际广泛认可的SHA—1算法实现1—Wire网络的安全认证,分析了其质询—响应认证过程,可将系统密钥存放在安全存储器中,而不必存放在程序代码内。这种系统便于扩展,DS2432的数据安全性甚至可以实现远程配置修改,节省设计时间,实现了低成本的安全认证功能。

| Abstract: | A novel method of the implementation of two-way authentication and software feature protection by DS2432 is pre- sented.At first,the paper analyzes the base principle of algorithm,and then introduces the design of a novel secure authentica- tion by using worldwide recognized SHA-1 algorithm in 1-Wire DS2432 net.Its inquiry and response authentication processes are analyzed.The system secret key can be stored in secure memory instead of in program code.The system can be extended easily, the data security of DS2432 can even be modified by remote configuration,and the secure authentication at low cost is imple- mented in the system. |
