Center node: "security in twin code framework"
  Abstract: Achieving reliability, availability, efficient node repair and security of the data stored in a Distributed Storage System (DSS) is of great importance for improving the functioning of these systems. In this work, we apply a data distribution concept, Twin-code framework, and compare it with a DSS that uses minimum bandwidth regenerating (MBR) and minimum storage regenerating (MSR) codes. We demonstrate that the Twin-code framework gives better performance in the distribution process. Moreover, we construct a new secure Twin MDS code and investigate its security performance comparing to the security of the MBR and MSR codes. The new constructed code is resistant against a threat model where a passive eavesdropper can access to the stored data and the downloaded data during the repair process of a failed node. We demonstrate that the Twin MDS code framework achieves better results than the MBR and MSR codes regarding the security in the system.
