- WirelessHART is the first open standard for wireless sensor networks designed specifically for industrial process automation and control systems. WirelessHART is a secure protocol; however, it relies on a Security Manager for the management of the security keys and the authentication of new devices. The WirelessHART standard does not provide the specification and design of the Security Manager. Also, the security specifications in the standard are not well organized and are dispersed throughout the standard which makes an implementation of the standard more difficult. In this paper we provide the detailed specification and design as well as an implementation of the Security Manager for theWirelessHART standard. We evaluate our security manager against different cryptographic algorithms and measure the latency between the Network Manager and the SecurityManager. Our evaluation shows that the proposed security manager meets theWirelessHART requirements. Our analysis shows that the provided Security Manager is capable of securing both the wireless and wired part of the WirelessHART network.

Konferensbidrag (refereegranskat)abstract
- WirelessHART is a secure and reliable communication standard for industrial process automation. The WirelessHART specifications are well organized in all aspects exceptsecurity: there are no separate specifications of security requirements or features. Rather,security mechanisms are described throughout the documentation. This hinders implementation of the standard and development of applications since it requires profound knowledge of all the core specifications on the part of the developer. In this paper we provide a comprehensive overview of WirelessHART security: we analyze the providedsecurity mechanisms against well known threats in the wireless medium, and propose recommendations to mitigate shortcomings. Furthermore, we elucidate the specifications of the security manager, its placement in the network, and interaction with the network manager.
