Security analysis of WIA-PA protocol

Abstract

The WIA-PA protocol is a secure and reliable communication standard for industrial process automation. WIA-PA standard defined on the security, but the description of the key management is not in detail, and there are security limitations in the kind of key management and authorization process. In this paper, we analyze the provided security mechanisms against well-known threats in wireless medium, and propose recommendations to mitigate the shortcomings. Finally, it summarizes concluded WIA-PA network security issues and the limitations of the security mechanism. This paper provides a reference for the WIA-PA network designer in security. © 2014 Springer-Verlag Berlin Heidelberg.
