Abstract

The invention discloses a high-speed wireless data secure transmission system and method suitable for a distribution network system. The secure transmission system comprises a distribution network automation system, a data transceiving and forwarding module, a composite security bridging module, a 3G wireless communication module, an individual line APN and a plurality of FTUs. According to the security protection level of a power system network, the end-to-end data encryption technology and the individual line APN technology are selected to guarantee the security of the network environment and data. An SIM card used for a private network only uses the dedicated APN, and usage of other APNs is limited; in other words, the SIM card will not be connected with the Internet in the data transmission process; in addition, the individual line APN and the Internet are two network structures completely stripped, and the end-to-end data encryption technology is adopted between the FTUs and a server platform; in this way, possible leakage of information in the whole transmission process is avoided, the security of the network environment is guaranteed, and meanwhile the security of data transmission is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a high-speed wireless data secure transmission system and method suitable for a distribution network system. Background technique [0002] With the gradual deepening of power grid reform and construction, the grid structure of the power system is becoming more and more reasonable. The primary network, secondary and tertiary networks have basically stabilized, and the equipment level and power supply reliability of the main network have been greatly improved. However, as the main bridge between the power supply company and the electricity customer - the distribution network line, its power supply reliability, automation, and information security still need to be improved and improved. [0003] To this end, closely around the key task of "preliminary completion of distribution network automation" proposed by the State Grid Corporation of China, strictly impleme...
