    • PURPOSE: A distribution automation system and a security algorithm application method thereof are provided to safely protect a distribution system from a cyber attack by executing an authentication operation before decoding data packet. CONSTITUTION: A distribution automation system comprises a distribution automation server(10) and a terminal(20). A distribution automation server is connected to a power distribution communications network(N1,N2) through a communications modem. A receiving node transmits a control message to a receiving node after appending authentication data to a control message. The receiving node decides whether data packet received from the transmission node is valid. The receiving node deciphers the control message included in the data packet when the data packet received from the transmission node is valid.
    • 目的:提供一种配电自动化系统及其安全算法应用方法,通过在解码数据包之前执行认证操作来安全地保护配电系统免受网络攻击。 规定:配电自动化系统包括配电自动化服务器(10)和终端(20)。 配电自动化服务器通过通信调制解调器连接到配电通信网络(N1,N2)。 接收节点在将认证数据附加到控制消息之后向接收节点发送控制消息。 接收节点决定从传输节点接收的数据分组是否有效。 当从传输节点接收的数据分组有效时,接收节点解密包含在数据分组中的控制消息。
