Several security mechanisms have been investigated and deployed that provide protection for real time platforms. Each security mechanism is contributed to enhance the SCADA system security, but at the same time, the mechanism is limited and depended on the other protocols for the purposes of message security, and its delivery. Few researches are conducted(More)
In Industrial systems, Supervisory control and data acquisition (SCADA) system, the pseudo-transport layer of the distributed network protocol (DNP3) performs the functions of the transport layer and network layer of the open systems interconnection (OSI) model. This study used a simulation design of water pumping system, in-which the network nodes are(More)
In this paper, we introduce a novel self-routed wavelength-addressable switching network (SWANET) that provides wavelength-transparent optical data paths between end-points, conng-ured by wavelength-coded optical signals. The network is based on a new scheme for encoding destination addresses using a sequence of wavelengths. This allows large networks to be(More)
