MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202647073242 A) filed by Qualcomm Incorporated on June 12, 2026, for Techniques To Support Security For Store And Forward Satellite Access.
Inventors include Edge Stephen William; Escott Adrian Edward; Lee Soo Bum; and Zisimopoulos Haris.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: To support secure access of a user equipment (UE) to a satellite operating in a store and forward mode the satellite may send an authentication request to the UE that includes a portion of a key identifier (ID) which may be least significant bits. The portion of the key ID and a derived key may be configured in the satellite. The UE may reconstruct the key ID based on the portion of the key ID and may determine the derived key from the key ID and a master key provisioned to the UE. The satellite may authenticate an identity (e.g. an international mobile subscriber identity (IMSI) or subscription permanent identifier (SUPI)) for the UE using the derived key. For accessing a home network of the UE a second identity and a second key for the UE may be used to avoid exposing the master key to a serving ground network.
