APPLICATION OF SECURE ELEMENTS TO ENHANCE REAL-TIME CONTINUOUS MONITORING AND CONFIGURATION

Rowland, Michael T.; Karch, Benjamin K.; Maccarone, Lee M.

The research investigates novel techniques to enhance supply chain security via addition of configuration management controls to protect Instrumentation and Control (I&C) systems of a Nuclear Power Plant (NPP). A secure element (SE) is integrated into a proof-of-concept testbed by means of a commercially available smart card, which provides tamper resistant key storage and a cryptographic coprocessor. The secure element simplifies setup and establishment of a secure communications channel between the configuration manager and verification system and the I&C system (running OpenPLC). This secure channel can be used to provide copies of commands and configuration changes of the I&C system for analysis.
