The AGU is built on L3Harris’ decades of heritage in spacecraft communications and encryption products.
Our products have decades of cumulative on-orbit performance beyond mission life and have never caused a mission failure. To date, more than 100 AGU units have been delivered or are currently under contract to be delivered.
The encrypt and decrypt interfaces are separate, and packets can be simultaneously passed to the AGU for encryption and decryption. This AGU is fully compatible with the Common Communications for Visiting Vehicles protocol used on the International Space Station, as well as other AES-GCM links. A pair of AGUs can be used to secure a channel.
The AGU is a NIST 140-2 validated encryption unit using an Advanced Encryption Standard (AES) block cipher operating in Galois Counter Mode (GCM). This stand-alone unit localizes all security requirements for level 2 into one box.
