Abstract: Techniques are disclosed relating to securely storing file system metadata in a computing device. In one embodiment, a computing device includes a processor, memory, and a secure circuit. The memory has a file system stored therein that includes metadata for accessing a plurality of files in the memory. The metadata is encrypted with a metadata encryption key that is stored in an encrypted form. The secure circuit is configured to receive a request from the processor to access the file system. In response to the request, the secure circuit is configured to decrypt the encrypted form of the metadata encryption key. In some embodiments, the computing device includes a memory controller configured to receive the metadata encryption key from the secure circuit, retrieve the encrypted metadata from the memory, and decrypt the encrypted metadata prior to providing the metadata to the processor.

Abstract: A matchmaking service can match a satellite owner/operator with antennas that are available and capable of servicing a communication request from the satellite owner/operator (e.g., to exchange data with the satellite owner/operator's satellite). The communication request may be received at a ground station service, and information included therein may be compared to capabilities of antennas registered with the ground station service to determine antennas that are compatible with the request. The ground station service may reserve a time slot for a selected compatible antenna to service the request and control the selected compatible antenna (e.g., to track and communicate with the satellite) during the time slot. In some embodiments, the matchmaking of satellite owners/operators to antennas uses models to determine communication parameters for a communication request and to determine capabilities of antennas registered with the ground station.
