The Ground Encryption Interface Unit (GEIU) is a custom encryption and decryption interface unit. The GEIU provides a network interface to the latest lines of Ground Encryption Units.
- Provides a LAN interface to facilitate access by multiple computers to the Ground Encryption Unit (like KIV-7M) over the LAN (both collocated and remote).
- Translates data received over the Local Area Network (LAN) using TCP/IP communications socket protocol into the clock, data, gate protocol used by a Ground Encryption Unit using its RS-422 ports.
- Enables the connection of an Ethernet Interface to a Ground Encryption Unit.
- Two Channels.
- Provides a key management function to map spacecraft and key indices to memory locations within a Ground Encryption Unit. This supports using the same Ground Encryption Unit for multiple spacecraft and eliminates the need for key management by an external control computer.
