Secure Data Link

Certain confidential and top secret information in transit must be secured stronger than conventional security systems may provide


EIDEL’s Secure Data Link (SDL) is a hardware based encryption system designed to add security to EIDEL Distributed Data Acquisition System (EDDAS) or to work as a stand alone security system where there is a requirement for end-to-end encryption in remote locations and harsh enviroments.

The system includes a compact and rugged encryption devices called EDDAS Crypto Units (ECU) that provides a symmetrical end-to-end encryption, protecting information up to and including SECRET. It is connected as a Ethernet interface, and the protected information is wrapped in the CCSDS TM space protocol, which is well suited for radio transmission.

Used on autonomous systems it can encrypt images, video, location data and other information in the data stream if the radio transmission or network connection allows sufficient data flow.

End-to-end encryption protection prevents unauthorized dissemination of information, whether the autonomous system portrays the situation at an injury site or follows people who should be unaware of the surveillance.

The protected data stream can be routed to one or more reception locations, whether fixed, mobile or flying. The solution can protect previously communicated information even if the drone crashes or ends up on unauthorized hands. With two-way radio-based network connection, communication can be protected in both directions. It will not be possible to take control of the autonomous system in an unauthorized manner if it is controlled in this way. In addition, communication over networks can easily be done over great distances, and drone control from one common location for the entire country is thus a possibility.
