Secure Data Transmission Increases Air Traffic Management Safety

Secure Data Transmission Increases Air Traffic Management Safety

An Air Traffic Management (ATM) system, which refers to the entirety of systems and actions required to manage the movement of aircraft both on the ground and in the air, plays a major role in maintaining secure aeronautical transportation. System integrators for ATM systems need to build a secure communication network for acquiring serial, digital, and analog data from runway lights, tower lights, and navigation aids, so that the data can be transmitted in real time to the control center.


Airport facilities use sensors to collect data from field sites that are accustomed to using OT protocols such as Modbus, and in many cases are not designed with transmission security in mind. Some governments require high-profile areas like airports to encrypt Internet-facing data transmissions. The major challenge to establishing a secure communication system between a control center and airport facilities is how to securely acquire data using IT protocols that receive the data from OT systems.


Designed to make system integration easy, we need smart IO modular are not only capable of collecting both serial Modbus and I/O data, they also come with SNMPv3 and SNMPv3 Trap protocols that support user authentication and SHA224 and SHA256 encryption algorithms to ensure that your remote I/O devices and the data transmitted between field devices and the control center are secure.

Data Protection

• Advanced modular remote I/O products that support SNMPv3 and SNMPv3 Trap for secure dual-direction data transmissions.

• SNMPv3 that supports SHA224 and SHA256 encryption algorithms to minimize the risk of data leakage.
