On the one hand, this trend increases the need for an automation-friendly security solution, as such networks can no longer be considered sufficiently isolated. On the other hand, it shows that, despite diverging requirements, the domain of Operational Technology (OT) can derive advantage from high-volume technology of the Information Technology (IT) domain. Based on these two sides of the same coin, we study the challenges and prospects of approaches to communication security in real-time Ethernet automation systems. In order to capitalize the expertise aggregated in decades of research and development, we put a special focus on the reuse of well-established security technology from the IT domain. We argue that enhancing such technology to become automation-friendly is likely to result in more robust and secure designs than greenfield designs. Because of its widespread deployment and the (to this date) nonexistence of a consistent security architecture, we use PROFINET as a showcase of our considerations. Security requirements for this technology are defined and different well-known solutions are examined according their suitability for PROFINET. Based on these findings, we elaborate the necessary adaptions for the deployment on PROFINET.","PeriodicalId":350991,"journal":{"name":"2018 14th IEEE International Workshop on Factory Communication Systems (WFCS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128965796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the industrial scenario, with strict demands on end-to-end latency and reliability during critical events, these technologies can be leveraged to construct chains of network functions (service graphs) characterized by guarantees about latency, jitter, packet loss or redundancy. Moreover, real-time monitoring techniques provided by network virtualization help in mitigating critical events (e.g. failures or network attacks), which can be faced by updating the service graph and imposing new policies in the network. In practice, the distributed and safety-critical nature of IIoT applications requires both an intelligent placement of services across physically separated locations, which has a direct impact on latency, and a proper policy enforcement system, which guarantees service reliability, safety, and security. This paper considers both aspects by proposing a novel Virtual Network Function (VNF) placement solution for IIoT that minimizes the overall latency and, at the same time, also verifies that network-wide policies such as connectivity or isolation hold between the endpoints. In particular, this work relies on recent advances in SMT (Satisfiability Modulo Theories) solvers, which are being enhanced to solve the Maximum Satisfiability (MaxSAT) problem.","PeriodicalId":350991,"journal":{"name":"2018 14th IEEE International Workshop on Factory Communication Systems (WFCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129138477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Minimized and nearly deterministic end-to-end latency allows centralized real time data recording and actuator control. Moreover, defined latency improves security and safety mechanisms to come closer to the trustworthiness of a cable while realizing the advantages of wireless networks. Battery powered or energy harvesting wireless nodes are inevitable to avoid power lines and therefore, we cope with limited energy budgets. In order to balance the communication load among sufficiently supplied nodes, the energy budget is part of the routing path metric. We show that the time domain multiple access scheme is crucial to enable defined latency and improve energy efficiency by avoiding collisions. If the energy distribution among the nodes is known, this novel protocol allows to calculate latency and round-trip time in advance. An asymmetric timing scheme can limit multi-hop latency for either upstream or downstream communication by one superframes (SF) duration. The presented ruleset is able to reconfigure the routing focused on energy constraints of involved nodes.","PeriodicalId":350991,"journal":{"name":"2018 14th IEEE International Workshop on Factory Communication Systems (WFCS)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124421290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These modelling technologies already reduce integration efforts as they provide a common Application Programming Interface (API) to handle and access properties and methods that are exposed by applications running on the CPS. These properties and methods can be structured and enriched with semantics within an information model. The integration of the information model with the application is still a quite complex task that typically requires comparable large manual programming efforts and additional components to manage the interaction between application and model. This work targets especially at more complex applications that shall be configurable through the information model — therefore a use case of a configurable state-machine is discussed in this work. To manage the interaction between such a dynamic application and an information model, a tight coupling of both is required. This work targets at re-use and integration of application code with information modelling based on annotations added to the application code. As a result, the object-structure and the (business) logic of the objects is integrated with the model. Finally, the external consumer can not only read, write and browse the exposed properties and methods of the application, but also create, update and delete objects within the object-structure with minimal additional manual efforts.","PeriodicalId":350991,"journal":{"name":"2018 14th IEEE International Workshop on Factory Communication Systems (WFCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131239265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a dedicated measurement hardware the highly dynamic power consumption of wireless embedded systems can be tracked over 5 decades from μW in low power sleep modes up to several hundreds of mW during RF transmission and full processor activity. Further, as IWSANs have high demands on synchronicity and low latency, our testbed allows automated measurements to evaluate synchronization accuracy and latency within the network with a time granularity of 125 ns and thus meets most industrial requirements. For this we use an Industrial RealTime Ethernet (RTE) network. Our combination of distributed ethernet-connected power measurement circuits with the RTE system allows a network-wide synchronized acquisition of the sensor nodes power consumption and supply voltage waveforms of all observed nodes. The wired RTE and Ethernet networks guarantee a scalable measurement setup and are not in conflict with the wireless devices under test. We demonstrate the usability of the proposed measurement setup by means of investigating two different heterogenous setups of real-world wireless networks. First we analyze the timing behavior of distributed standardized ZigBee nodes exclusively based on their power consumption measurements. And in contrary we present a proprietary industrial WSN dedicated to low power consumption and high sampling synchronicity of the individual nodes and evaluate their synchronization performance.","PeriodicalId":350991,"journal":{"name":"2018 14th IEEE International Workshop on Factory Communication Systems (WFCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130246682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, design of FA systems that employ wireless networks involves stringent constraints on real-time performance and reliability, and requires the assessment of and experimentation with complex interactions among process control, factory topology construction (layout and connectivity of subsystems, such as machines, rails, etc.), and wireless communication. In this paper, we introduce a novel simulation framework to support such assessment and experimentation in the design of next-generation FA systems. Our simulation framework employs model-based design principles to enhance design reliability, and enable systematic and efficient integration of control, topology, and network modeling aspects. We demonstrate the utility of our framework through a case study that involves topology design and scalability analysis for a large class of FA systems. Our results demonstrate the ability of the proposed framework to provide insights on complex design trade-offs, while the underlying model-based features enhance efficient and reliable system-level integration.","PeriodicalId":350991,"journal":{"name":"2018 14th IEEE International Workshop on Factory Communication Systems (WFCS)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126668024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
