The M4Com Crypto Device software module is used for encrypted, bi-directional communication between two processing systems connected to the MCD 2-1/1 Crypto Device modules. The device is used in the context of sending or forwarding a live video export stream or data as well as for de-coupling systems relevant to flight approval from processing systems through an integrated data diode. Accordingly, the CrytoDevice ensures end-to-end encryption for the secure transmission of sensitive information via public communication networks or radio transmissions.
The MCD 2-1/1 Crypto Device module has two operating modes, which can run simultaneously. Mode 1 establishes a secure encrypted network connection between the internal Ethernet network inputs (network RJ45 INT) of two MCD 2-1/1 Crypto Device modules in 2 separate stations. Mode 2 distributes data unidirectionally present at the internal diode network input (Diode IN INT) to the internal network connection (network RJ45 INT) and to the external encrypted network connection (network LWL EXT).
