FPGA-based Real-time Abnormal Packet Detector for Critical Industrial Network
2019 IEEE Symposium on Computers and Communications (ISCC), 2019Co-Authors: Jiwoong Kang, Jaehyun ParkAbstract:As the information technology plays an important role in the smart factories, Ethernet-based Industrial Network has rapidly replaced the traditional field buses. To maintain this critical Network secure, it is important to develop the realtime Network intrusion detection system (NIDS). The widely used NIDS was developed for the general Internet environment where the average throughput to protect attacks from the large number of unknown Network nodes is more important than the real-time detection capability. However, in the critical Industrial Network, the real-time protection is more important than the average throughput. In this paper, a FPGA-based abnormal Ethernet packet detector is proposed. Since it is designed for the closed industry Network, packet detection is based on the whitelist that consists of the allowed Network address and protocol numbers. The prototype system has been implemented using the Xilinx Zynq-7030 SoC running at 250MHz. The Network header of the Ethernet packet is compared to the 256 whitelist ruleset within 0.032μsec, which means that the malicious packets from the abnormal Network nodes are filtered out even before the whole packets arrives. This real-time packet filtering feature is useful in protecting highly secure Network systems like the critical Industrial control systems.

Ring Topology-based Redundancy Ethernet for Industrial Network
2006 SICE-ICASE International Joint Conference, 2006Co-Authors: Geon Yoon, Dae Kwon, Soon Young Kwon, Yong ParkAbstract:Recently Ethernet system is getting very high attention for Industrial Network. Industrial customers are no longer satisfied with RS232 or RS485 data transmission; rather they are demanding the benefits of Ethernet connectivity. However the star topology of Ethernet is not flexible and not reliable for Industrial Network because of dependency on switch or hub. This paper proposes the redundancy Ethernet system based on ring topology without switch or hub. And also proposes the new topology adaptation Network management protocol (TANMP). The topology of the proposed redundancy Ethernet system can be flexibly changed from the ring topology to the line (daisy-chained) topology or opposite case. And also guarantees packet-transmission to its destination in spite of a link-fault. TANMP supports the simple hop count based routing function with high performance and manages Network topology with minimum recovery time. In this paper, we implement the proposed TANMP and analysis performance of the proposed ring topology based redundancy Ethernet system for Industrial Network.

On-Demand Transmission for Edge-Assisted Remote Control in Industrial Network Systems
IEEE Transactions on Industrial Informatics, 2020Co-Authors: Cailian Chen, Xinping GuanAbstract:Sensing data and control commands are frequently exchanged over communication Networks for remote data acquisition and distributed control in Industrial Network control systems. The system performance relies on the design of sensing, transmission, and control. Due to the harsh environment in Industrial field and the limited Network resources, it is very challenging to meet the high requirement on transmission reliability for remote feedback control. In order to enhance the transmission ability for this kind of systems, an edge-assisted system architecture is proposed for the sensing and control processes. The parameter estimation for the sensing process is executed in the so-called edge estimator, and the controller is designed in a remote control center. Under this architecture, in this article an on-demand transmission scheme is designed by characterizing the overall effects of transmission reliability on the estimation and control performance. The overall system is optimized by formulating a revenue-cost maximization problem subject to the constraints of system stability, estimation convergence, spectrum utilization, and energy budget. The formulated mixed-integer nonlinear programming problem can be effectively solved with the block coordinate descent method. It is decomposed into two subproblems over disjoint variable sets. Simulation results demonstrate the advantages on both Network-wide revenue and control-transmission cost.

Sensing Aware Opportunistic Transmissions for Situation Monitoring in Industrial Network Systems
2019 IEEE Global Communications Conference (GLOBECOM), 2019Co-Authors: Cailian Chen, Xinping GuanAbstract:State estimation plays an important role for the situation monitoring in Industrial Network systems, where multiple sensors observe a dynamical process and deliver state information to the remote center over wireless channels. However, the lossy wireless channels make the state information received by remote center be intermittent. Moreover, the scarcity of radio resources makes it challenging to simultaneously schedule a large number of sensors. In practice, different sensors usually have distinct contributions on state estimation, thus this paper firstly characterizes the integrated impact of sensing ability and transmission capacity on the state estimation performance, based on which a sensing aware opportunistic transmission scheme is then proposed. At each discrete time instant, the remote center determines which sensors to schedule based on the estimation demand and radio resources, and each sensor decides whether to participate the data transmission according to its residual energy. In order to further enhance the estimation performance and resource efficiency, the transmission scheduling and the sensor participation are jointly optimized by formulating a Network-wide revenue maximization problem. This mix-integer nonlinear programming problem is effectively solved with the Dinkelbach method and heuristic algorithm. Finally, numerical simulation results verify the scheme efficiency.
