Abstract
In recent years, industrial automation has been established and WISN (Wireless Industrial Sensor Network) has been introduced for efficient system management. By introducing WISN, many engineering costs have been reduced and process processors have been optimized. And communication flow using wireless is increasing. An empirical study on industrial wireless sensor networks is actively conducted, but there are few security studies on them and they are exposed to such threats. If there is a problem with the standard of the wireless communication protocol itself, the device that is certified according to the standard may also be subject to security threats including problems. We analyze security functions and threats of ISA 100.11a and WirelessHART protocol stack based on standards. Procedures for distributing the security key are not provided or it is vulnerable using the Global Data Link key when the device enters the network. This paper presents the problems of the standard itself and presents the security requirements accordingly.
