摘要
介绍了加密芯片NRSEC3000的特点、读写工作原理以及微处理器对NRSEC3000进行操作时的硬件接口电路和底层驱动。详细阐述了芯片与状态接入控制器(CAC)之间的秘钥协商软件设计流程,成功实现了以SM1、SM2算法为核心的混合加密协议,有效提高了加密系统的效率与安全。最后讨论了该芯片在电压监测仪安全防护中的应用。
Introduces the features, read and write operation of encryption chip NRSEC3000, as well as the hardware interface circuit and drivers between microprocessor and NRSEC3000. The software design process of key agreement when accessing to condition acquisition controller （CAC） is explained in detail. The mixed cryptosystem security protocols based on SM1 and SM2 algorithms is successfully implemented and effectively improves encryption-system＇ s speed and safety. Finally the application of encryption chip NRSEC3000 in voltage monitor security protection is discussed.
