The invention relates to a power line carrier system. A method is characterized in that the system comprises a main control device and an interface backboard; the interface backboard is connected withthe main control device; the interface backboard is provided with an indicating device, a user interface module, an issuing interface module and a power line interface module. The main control deviceis used for receiving a key writing request sent by a key issuing terminal through the issuing interface module; the authentication module is also used for carrying out equipment identity authentication on the key issuing terminal when the key writing request is received; when the equipment identity authentication is passed, key data sent by a key issuing terminal is received through the issuinginterface module; the key data is written into the security chip; wherein the key data is used for the security chip to encrypt the sensitive data processed by the main control module. By adopting themethod, the safety degree of the power line carrier communication process can be improved.
Description
technical field [0001] The present application relates to the technical field of power carrier safety, in particular to a power carrier system. Background technique [0002] Power carrier communication is referred to as PLC (Power line Communication). Power carrier is a unique communication method of power system. Power carrier communication refers to the technology of high-speed transmission of analog or digital signals by means of carrier wave using existing power lines. The biggest feature is that there is no need to re-establish the network, as long as there are wires, data transmission can be carried out. [0003] However, in the process of manufacturing the carrier module, the sensitive key data of the carrier module often needs to be written by the manufacturer, and the sensitive key data is controlled by the manufacturer, which has a large security risk and affects the safety of the power carrier communication. [0004] Therefore, the security level of the existing...
