Abstract:
1. A method in a data network for authenticating identifying data transmitted from a client to a domain server through use of a gateway interface system which are communicatively coupled to each other, said method comprising the steps of: intercepting an authentication packet transmitted from a client to a domain server by the gateway interface, wherein said authentication packet is symmetrically encrypted by the client with a one-time password for transmission from said client to said domain server; verifying said one-time password associated with said authentication packet by the gateway interface based upon a plurality of preassigned one-time passwords either cached or accessed from at least one authentication server; and modifying said authentication packet by the gateway interface for acceptance by said domain server, wherein the response packet that is generated by said domain server is thereafter intercepted, verified and modified by said gateway interface for transmission back to the client.
