摘要
ESAM安全芯片是智能电表中最重要的组成部分,可以利用固化于ESAM安全芯片中的加密算法对用户、电表的关键信息数据进行加密,增强电表的安全性。本文主要讨论ESAM安全芯片在电表中的应用。首先介绍ESAM安全芯片性质和内部结构;然后设计ESAM与电表的通信;最后,设计了ESAM芯片与电表进行身份双向认证、充值、扣费、参数设置与远程控制的软件操作流程。
ESAM security chip is the most important part of smart meters. It can use in curing ESAM secure chip encryption algorithm to encrypt the key of information data user in the electric meter. So it can enhance the safety of the electricity meters. This article mainly discusses ESAM security chip in the application of the meter. First it introduces ESAM security chip properties and internal structure. Then it designs the ESAM with meter communication. Finally, it designs the operation processes, for example, the ESAM chip and electric meter in twoway identity authentication, top-up, deduction, parameter setting and remote control.
