Wireless systems in general require additional and different engineering and maintenance tasks for example cryptographic key management. This is an important aspect that needs to be addressed before wireless systems can be deployed and maintained efficiently in the industry. In this paper we take an holistic approach that addresses safety and security regardless of the underlying media. In our proposed framework we introduce security modules which can be retrofitted to provide end-to-end integrity and authentication measures by utilizing the black channel concept. With the proposed approach we can extend and provide end-to-end security as well as functional safety using existing automation equipment and standards such as Profisafe Profinet IO and WirelessHART. Furthermore we improve the WirelessHART standard with periodic and deterministic downlink transmissions to enable efficient usage of wireless actuators as well as improving the performance of functional safety protocols. 1. Introduction Recently the automation industry has shown a strong interest in migrating substantial parts of the traditionally wired industrial infrastructure to wireless technologies to improve flexibility scalability and efficiency with a significant cost reduction. The main concerns about reliability security integration along with the lack of device interoperability have hampered the deployment rate. To address these concerns WirelessHART 1 the first open
