Abstract
A communications system may include a satellite constellation and a terrestrial network that convey text messages between first and second user equipment (UE) devices. The terrestrial network may include a core network, an inter-working function (IWF) server, and carrier networks. The IWF server may distribute keys and the first UE device may transmit provisioning data to the core network while the first UE device is on-grid. When the first UE device goes off-grid, the first UE device may transmit an escrow key to the core network for use in decrypting a device public key from the provisioning data. The core network may transmit the device public key and other information to the IWF for use in routing messages via the NTN. The core network may use the handles to enforce an allow list that filters traffic to the first UE device over the NTN.
