Abstract

The invention relates to a message data transmission method, device and system. The method comprises the steps of determining a sending end identifier and a receiving end identifier of to-be-sent message data; determining a target tunnel identifier based on the sending end identifier and the receiving end identifier; extracting verification information from a tunnel table based on the target tunnel identifier; establishing a target tunnel between the sending end and the receiving end based on the verification information and generating a session key; encrypting the message data through the session key to generate encrypted data; and sending the encrypted data to the receiving end through the target tunnel. According to the message data transmission method, device and system provided by theinvention, the problem of insufficient security in the existing terminal can be overcome, and confidentiality and integrity protection is provided for transmission of the message data between the terminals.

Description

technical field [0001] The present disclosure relates to the field of computer information processing, in particular, to a message data transmission method, device and system. Background technique [0002] In recent years, thanks to the support of national policies, China's new energy industry has developed rapidly. As the proportion of photovoltaic power generation in primary energy consumption continues to increase, its safe operation is becoming more and more important. Therefore, the power system also puts forward higher requirements for new energy access to the grid and related secondary protection. Among them, for the monitoring system not covered by the dispatching data network, such as load management, distribution network automation, and data communication of distributed power access, the power dedicated communication network is preferred. If the conditions are not available, the public communication network can also be used (not Including the Internet), wireless p...
