Application of encryption technology in RTU data acquisition

With the rapid development of the Internet of Things, wireless network communication technology has reached a historical height, but in the face of more and more open network environment, data transmission security is more and more challenging. Due to hacking or interception of data and other reasons, it is very easy to have data loss leakage, resulting in significant consequences will be very large, through the application of secure transmission technology, to a large extent, can effectively prevent data leakage caused significant economic losses.

At present, the widely used data transmission security technology is mainly: physical security analysis technology, network structure security technology, system security technology, management security technology, and its security services and security mechanism strategy. However, with the security technology is not enough, so we have to have network security awareness and establish a corresponding security mechanism. Such as: encryption mechanism, access control mechanism, data integrity mechanism to ensure network security.

Because RTU Wireless acquisition transmission unit, is generally used in power, water conservancy, transportation, finance, agriculture, forestry, coal, petrochemical, environmental monitoring and protection, meteorology, fire, public safety, smart home, automation and other fields. The security and accuracy of data transmission is very important to all walks of life, so RTU data acquisition and transmission need to ensure the accurate arrival of data to the designated location, and can not be modified in the middle of the use of others. Therefore Xiamen developed for that RTU encryption device born.

RTU for the English remoteterminalunit abbreviation, RTU is also known as the Remote Terminal Control unit, mainly responsible for the field signal, industrial equipment monitoring and control. Xiamen for the development of the RTU data acquisition terminal powerful, interface support 232/485/ttl, while supporting the current acquisition and voltage acquisition. RTU uses an industrial-grade 32-bit processor for hardware platforms and embedded real-time operating systems. and has a variety of encryption methods for data transmission encryption processing to ensure the user's data security, so the RTU in Xiamen has been widely used in all walks of life.
