A method and apparatus is disclosed for enhancing the security of a message sent through a network server from a client computer to a destination server. A secure connection for receiving and transmitting data is established between the client computer and the network server. Using client-identifying information and a secure authentication protocol, the network server may then obtain client-authentication information from a validation center. The client-authentication information is transmitted to the client and erased from the network server. The network server then receives the client-authenticating information back from the client with an accompanying message for the destination server. The network server may use the client-authenticating information to obtain permission data from the validation center for use in accessing the destination server.
