Abstract

Existing Supervisory Control and Data Acquisition (SCADA) networks are not designed with security in mind. Traditional SCADA controllers react in an automated way that is oblivious to unanticipated malicious attacks, component malfunctions and other byzantine failures. A fast method is needed that takes trust into account in SCADA control systems. In this article, we develop the Simple Trust protocol to allow for low computational and bandwidth cost in evaluating trust between SCADA components and demonstrate (through simulation) its capability to meet SCADA critical timing constrains. This type of system is a first step towards more sophisticated SCADA controllers, which can proactively operate under malicious attacks and failure conditions.
