sSCADA: Securing SCADA Infrastructure Communications
Yongge Wang and Bei-Tseng Chu
Abstract: Distributed control systems (DCS) and supervisory control and data
acquisition (SCADA) systems were developed to reduce labor costs, and
to allow system-wide monitoring and remote control from a central location.
Control systems are widely used in critical infrastructures such as electric
grid, natural gas, water, and wastewater industries.
While control systems can be vulnerable to a variety of types of cyber
attacks that could have devastating consequences, little research
has been done to secure the control systems. This paper presents a suite
of security protocols optimized for SCADA/DCS systems which include:
point-to-point secure channels, authenticated broadcast channels,
authenticated emergency channels, and revised authenticated
emergency channels. These protocols are designed to address the
specific challenges that SCADA systems have.
