Low-cost Internet-of-Things security protection method and terminal equipment

Abstract

The invention relates to the field of network information security, in particular to a low-cost Internet-of-Things security protection method and terminal equipment. The system comprises an internal processing module, an external processing module and a data exchange module, wherein the internal processing module, the external processing module and the data exchange module adopt pin structures and are combined in a splicing manner, the data exchange module is located between the internal data module and the external data module, and a data exchange node is established between an internal network and an external network; the three modules are provided with independent CPUs and do not interfere with one another during operation; and the data exchange module is provided with double data channels. Terminal equipment adopts a redundant extensible splicing structure, physical isolation and software verification are combined to ensure the security of internal and external network data transmission, and meanwhile, a distributed double-blockchain encryption technology is innovatively proposed to record network security intrusion information and share the information to other nodes in the network, so that the risk that the whole network is intruded is reduced.

Description

technical field [0001] The invention relates to the field of network information security, in particular to a low-cost Internet of Things network security protection method and terminal equipment. Background technique [0002] In recent years, the State Commission has requested to strengthen the data collection of 220 / 380V distributed photovoltaic power stations, to strengthen the exploration and development of wireless private network to realize distributed photovoltaic control technology research, to achieve considerable and measurable low-voltage distributed photovoltaics, and to gradually realize low-voltage distributed photovoltaics. Controllability. However, the capacity of distributed photovoltaic power plants is small, the investment ability of owners is weak, the economy of wireless private network transmission is not high, and the security of wireless public network transmission is not guaranteed. It can be seen that low-voltage distributed photovoltaic data acquis...

Problems solved by technology

However, the capacity of distributed photovoltaic power plants is small, the investment ability of owners is weak, the economy of wireless private network transmission is not high, and the security of wireless public network transmission is not guaranteed. It can be seen that low-voltage distributed photovoltaic data acquisition Safety and economy cannot be balanced at the same time

Similarly, in the auxiliary monitoring system of the intelligent station, the information acquisition method is sent to the IoT platform by the intelligent power distribution gateway through the 4G (APN) method through the Ethernet, and there is no network isolation device between the station network and the 4G (APN) network , the deployment of this kind of network is extremely vulnerable to attacks from the external network, leading to information security incidents where the production network (inside the station) is attacked, and there are serious security holes in the network architecture
