State secret encryption 4G cellular router based on IPSec VPN tunnel technology to ensure the security of power industrial control data

With the in-depth application of Industrial Internet of Things (IIoT) technology, power industrial control system is an important part of key infrastructure.Its data security has attracted more and more attention. In the power industrial control system, 4G cellular router is the key device for data transmission.Its encryption and security capabilities are critical to keeping data safe.This paper will discuss how the 4G cellular router based on IPSec VPN tunnel technology can effectively protect the security of power industrial control data.

First, the importance of power industrial control data security

The power industrial control system is responsible for monitoring and controlling the operation of the power system.The data involved include equipment status, operating parameters, control instructions and so on, which are highly sensitive and important.Once these data are leaked or tampered with, it may have a serious impact on the stable operation of the power system.It may even lead to safety accidents. Therefore, ensuring the safety of power industrial control data is the key to ensure the safe and stable operation of the power system.

2. Advantages of IPSec VPN tunnel technology

IPSec (Internet Protocol Security) Is an open VPN (Virtual Private Network) protocol.It provides strong data encryption and authentication,It can ensure the confidentiality, integrity and authenticity of data in the process of transmission.By constructing an IPSec VPN tunnel, a secure private communication channel can be established over a public network,The 4G cellular router is protected from external attacks when transmitting data.

III. Application of State Secret Encryption Technology

State secret encryption technology refers to the technology of data encryption using the encryption algorithm approved by the State Encryption Administration.In the electric power industrial control system, the state secret encryption technology is used to encrypt the data.The security of data during transmission and storage can be ensured.The combination of state secret encryption technology and IPSec VPN tunnel technology can further improve the security performance of 4G cellular router.And provides more reliable protection for the electric power industrial control data.
