  • DEVICE INDEPENDENT SECURE MESSAGING
    Publication number: 20220303250
    Abstract: Systems, devices, media, and methods are presented for device independent secure messaging. The systems and methods generate an encrypted message by encrypting message content, designated for a specified recipient, with an encryption key. The systems and methods select a set of recipient keys, associated with the specified recipient, from a plurality of member keys. For each recipient key, the systems and methods encrypt the encryption key to generate a set of encrypted keys and transmit the encrypted message and an encrypted key of the set of encrypted keys to one or more client devices associated with the specified recipient. The systems and methods then receive an acknowledgement indicating a termination status of the encrypted message.
