Détails

Wireless networks are expected to deploy into industrial automation systems due to advantages of wireless such as reducing cabling cost, capability to attach movable or rotational equipment and so on. Wireless network for industrial automation requires real-time communication and redundancy for reliability. Devices that are connected to wireless network for industrial automation have to perform with low energy consumption to satisfy intrinsic safety restrictions. In addition the wireless network system has to security functions to secure the communications. ISA100.11a [1] is a wireless network system that has those features of wireless network systems for industrial automation. It is based on based on IEEE 802.15.4, Wireless network systems that provide security functions have to authenticate and authorize wireless devices to connect to a wireless network. And the wireless network systems have to provide secure sessions for communication over a wireless network. Pre-shared key or PKI are used for authentication of the devices. Keys derived from a pre-shared key or public key calculation secure authorization and communication over wireless network. ISA100.11a also provides those security mechanisms to allow wireless device to join wireless network. A join method to use pre-shared key are widely deployed in actual wireless network systems of ISA100.11a. A pre-shared key is called “join key” in ISA100.11a. Security of join keys is crucial to secure a wireless network of ISA100.11a because a join key protects other keys that are used in the wireless network.
