Critical infrastructures such as oil and gas pipelines, the electric power grid, and railways, rely on the proper operation of supervisory control and data acquisition (SCADA) systems. The trend to interconnect SCADA system devices using networking technologies, however, has introduced additional entry points for malicious software, often via the Internet.(More)
In this paper we describe a methodology for implementing the phase of execution of artificial neural networks (ANN) in hardware devices. First, we show how the elements of a single neuron: multipliers, sum of products and transfer function are separated and constructed as VHDL entities. These entities are then interconnected to form a neuron that can be(More)
