Research and implementation on the security scheme of industrial wireless network

Industrial Wireless communications is emerging technology after the Fieldbus in industrial field. For industrial control application with wireless industrial technologies, the WIA-PA standard defines the protocol suite, system management, gateway, and security for low-data-rate wireless connectivity with fixed, portable, and moving devices supporting the limited power consumption requirements. In this paper we summary the security provision in the current standards. Then we present a new security architecture and security protocol based on WIA-PA standard. Furthermore, we design and implement the security communication services. Finally, the security test results illustrate that these security scheme may enhance the security reliability of the WIA-PA network communication.
