  • Patent number: 5968177
    Abstract: A method and apparatus for processing administration in a secure community, or communication system, is accomplished by dividing the single computing devices functionality of the administrator/officer/server into physically separate computing devices that function as a serving entity and an administrative entity. In the secure system, when an administrative entity has an administrative function to perform for one of its end-users, it requests a permissions matrix from the serving entity. The serving entity, after authenticating the administrative entity, sends the permissions matrix to the requesting administrative entity in an encoded format. The permissions matrix indicates which administrative functions the requesting administrative entity is authorized to perform for its affiliated end-users. Upon receiving the permissions matrix, the administrative entity verifies the authenticity of the permissions matrix based on the encoded format.
