  • Managing keys for encrypted shared documents
    Patent number: 9031876
    Abstract: A system administrator, while logged into a system-administrator account, creates and configures a key-administrator account and a member account. A key administrator, while logged into said key-administrator account, creates a group private key, a group public key, and a group symmetric key, a member private key, and a member public key. The key administrator encrypts the group private key with the group symmetric key, and encrypts said group symmetric key with the member public key. A publisher encrypts a document using the group public key. The publisher distributes the resulting encrypted group document so that it is accessible via said member account but not through said key-administrator account.
