摘　　要：随着智能电网技术的发展,配电自动化系统规模日益扩大,多种通信方式并存及所有报文均采用明文传输的通信方式导致系统受到各种网络攻击的风险较大,因此在配电自动化系统中引入了基于非对称加密技术的ECC椭圆曲线数字签名算法,在配电自动化系统的控制指令传输报文采用单向认证+数字签名的方式对系统进行防护,以免因系统攻击而影响系统的安全运行。With the development of smart grid technology and the increasing size of the distribution automation system, The coexistence of a variety of communication methods are used and all messages transmitted in the clear cause the system to be at greater risk of a variety of network attacks, therefore, we use the asymmetric cryptography ECC Elliptic Curve Digital Signature Algorithm for Security of the distribution automation system. In the distribution automation system control commands using one-way message transmission Certification with digital signature to the system protection, so as to avoid system attacks affecting the safe operation of the system. This paper describes the ECC Digital Signature Algorithm applications in distribution automation systems and it＇s implementations.
