Cryptographic Key Management for SCADA Systems, Issues and Perspectives

초록

영어

This article focuses on cryptographic Key Management Systems (KMS) for SCADA systems environments. It first gives a generic view on the constraints, requirements and desired technical properties in SCADA contexts. Then, the most widespread solutions are presented, before discussing how they meet such conditions. The work done by different initiatives on this issue is also introduced. Finally, perspectives and research directions are proposed in consequence. The article aims at presenting open issues on the area, to foster discussion and research, according to the authors’ view.
