Advanced Secure Supervisory and Data Acquisition (SCADA) and Realted Discribution Control Systems

The goal of this study is to attempt to place, where possible, highly efficient encryption and authentication algorithms in legacy devices already installed in the SCADA network. Where this is not possible, low cost inline security units will be proposed. On the larger scale, multi-level secure Internet protocols will be examined as a method to facilitate the sharing of control and status information between authenticated and authorized utilities and security agencies in times of crisis. This multilevel secure Internet protocol could allow a laptop computer with a properly authorized and authenticated operator to log on and view critical status information and begin immediate mitigation in the event of a major network issue even if both the primary and redundant control centers are inaccessible.
