BST Security & Redundancy
• Inmarsat Encryption
– Satellite air interface segment commercially
encrypted by the Inmarsat network
– NSA Type-1 encryption on satellite command links
• BST End to End Encryption
– AES 256 shared key
– User selectable for each interface individually
• User Encrypted Payloads
– BST delivers externally encrypted payloads
transparently
• Redundant Connection, Ground Station to Inmarsat
– Direct T1/E1, VPN, Mil Net, VSAT, Internet – Single Hop
– Satellite (BGAN) backup – Double Hop
