ABSTRACT:
Supervisory control and data
acquisition (SCADA) systems, are part of industrial control system (ICS), have
been playing crucial roles in real-time industrial automation and controls.
Through the evolution of 3rd generation, or networks based system, SCADA
systems are connected to almost types of networks such as wired, wireless, and
cellular and satellite communication, but security is still a big challenge for
SCADA system while communicating within. Internet of things (IoT) is a
ubiquitous platform, a new advance enhancement, for efficient SCADA system,
where billions of network devices, with smart sensing capabilities, are
networked over the Internet access. Deployment of smart IoT platform, SCADA
system will significantly increase system efficiency, scalability, and reduce
cost. Security is still a major issue for both-, as they were initially
designed without any priority and requirements of security. This study modeled IoT-SCADA
system and deployed a security mechanism, employing of cryptography based
algorithm, which provided a secure transmission channel while each time
communication occurred, between the field devices in the SCADA system. Proposed
security implementation, and computed measurements analyzed as potential
security building block against authentication and confidentiality attacks.
