Secure Staging System for Highly Confidential Data Built on Reconfigurable Computing Platform

Cloud use for High Performance Computing (HPC) and High Performance Data Analytics (HPDA) is increasing. The data are transferred to the cloud and usually left there even after the data being processed. There is security concern for such data being left online. We propose secure staging system to prepare not only data but also computing platform for processing the data dynamically just while the data is processed. The data plane of the secure staging system has dynamic reconfigurability with several lower-than-IP-layer partitioning mechanisms. The control plane consists of a scheduler and a resource provisioner working together to reconfigure the partitioning in the data plane dynamically. A field trial system is deployed for treating secure data in dental school to be processed in the computer center with the location distance of 1km. The system shows high score in the Common Vulnerability Scoring System (CVSS) evaluation.
