AES128 encription in XLRS System
Advanced Encrytion Standard (AES), is a standard commonly used for cryptography.
If AES 128 encryption is enabled, the radio system uses it in all data packets regardless of type.
The Radio Control information and the data of the radiomodem (Data Link Transparent) or Mavlink Telemetry are encrypted using this algorithm.
The AES128 license can be activated on almost all XLRS devices, they support 16-bit or 128-bit keys.
Radio range is not reduced when AES 128 is activated.
For encryption to work at least it must have 2 XLRS devices TX and RX with the AES128 license activated.
XLRS devices from 2020 already have encryption added in the system.
Most XLRS products that use the XLRS radio you can activate the AES128 encryption. (XLRS Analogue video systems can’t have encryption).
If encryption is used in the radio network system, all XLRS devices that intervene in the network must have the same key and must have the license activated.
The key is entered by the operator and only the operator has access to the keys.
The pilot does not have access to the encryption keys, only to his user password if previously the operator has activated the password on the XLRS device.
If the device doesn’t have the pasword activated, anyone will have access to the configuration of the device and can see the key.
To configure the encryption, it will be done through the DMDStudio software on each XLRS device.
