摘要

The system has a generation module to add a client security header in a non-secured request, for creating a secured request conforming to application communication protocol and sent to a server equipment (40). The header has security and authentication codes of a client equipment (20). A security management module (22) analyzes secured/non-secured response, conforming to the protocol, based on a server security header. An independent claim is also included for a process of secured communication between an automatic control client equipment and an automatic control server equipment.
