摘要: The present invention relates to a security system using an automatic meter reading protocol. The security system includes a Device Language Message Specification (DLMS) transmission unit for transmitting security DLMS data that includes security key update information and a first authentication value, and a DLMS reception unit for receiving the security DLMS data, searching the security key update information in the security DLMS data, and generating an updated security key using a second authentication value according to the security key update information. The security system can solve various problems occurring due to the operation of a separate security protocol, and can be easily implemented and managed.
