    Abstract: A communications system may include user equipment (UE) that transmits data to a recipient via a network. The UE may receive user input and may generate the data based on the input. When a terrestrial network is unavailable to the UE, the UE may transmit segments of the data over a satellite constellation as the UE continues to receive input and while connectivity to the constellation exceeds a threshold. If a portion of the input includes an edit to a previous segment, the UE may include an edit flag in the corresponding segment. Once input has finished, the UE may sign the segments and may transmit a signature over the constellation. The network may store the segments as received from the constellation, may replace edited segments with more recent segments containing edit flags, and may compile and transmit all of the segments to the recipient upon receipt of the signature.

    Abstract: Techniques are disclosed relating to secure message exchanges. In some embodiments, a first computing device generates an account key associated with a user account shared by a plurality of computing devices. The first computing device signs a public key of the first computing device with the generated account key to produce a digital signature and sends the public key and the digital signature to a first server system for distributing the public key to a second computing device attempting to send an encrypted message to the first computing device. The first computing device sends the account key to an external storage external usable by others of the plurality of computing devices to obtain the account key and use the account key to sign public keys of the other computing devices. The first computing device receives, from the second computing device, the encrypted message encrypted using the public key.

    Abstract: Techniques are disclosed relating to using a device to gain access to another system. In some embodiments, a first mobile device performs a pairing operation with a control unit that controls access to a system, the pairing operation including the first mobile device establishing a first cryptographic key with the control unit. The first mobile device receives a request to enable a second mobile device to communicate with the control unit, and in response to receiving the request, the first mobile device generates a second cryptographic key from the first cryptographic key. The first mobile device provides the second cryptographic key to the second mobile device. The second mobile device is configured to send a beacon including a payload encrypted with the second cryptographic key, and the encrypted payload is usable to authenticate the second mobile device to the control unit.
