A method for secure communications between first and second domains where a first logical unit calculates timestamps and hashes and transmits web forms to a node of a first domain responsive to a request. The first unit further receives data input to the web form by the user and enhances and translates that data and transmits the translated data across the public network. A second logical unit de-enhances the translated data, filters the translated data authorizes the filtered data and adds security services without modifying the application.
