  • User-session management in a zero-knowledge environment
    Patent number: 10904004
    Abstract: Examples of the present disclosure describe systems and methods relating to user-session management in a zero-knowledge environment. When a user authenticates with a computing service to begin a session, a credential-cipher key is used to encrypt the user's authentication credentials, thereby generating session-resume data. The computing service stores the credential-cipher key, such that it is not retained by the user's computing device. Accordingly, when the user resumes the session, a resume request is generated to retrieve the credential-cipher key from the computing service, wherein the request is validated before providing the key. Upon successful validation, the computing service provides the credential-cipher key, which is then used to decrypt the session-resume data and regain access to the user's authentication credentials.
