  • Publication number: 20260074890
    Abstract: An end-to-end encrypted communication system securely provides session keys for encrypted session history recovery for new members or reconnecting members of an encrypted session. The encrypted session history recovery adapts the end-to-end encryption for secure distribution of the encrypted content and session keys that were exchanged before the members connected to the encrypted session. The system receives encrypted content from a first member of the encrypted session during a first time when the first member is online and a second member of the encrypted session is offline and not connected to the encrypted session. The system detects that the second member comes online and connects to the encrypted session at a second time, and provides the second member with a session key associated with decrypting the encrypted content that was exchanged prior to the second member connecting to the encrypted session.
