Executive Summary

This paper presents evaluation results for a high security disaster recovery system using distribution and rake technology. In an experimental evaluation, the encryption and spatial scrambling performance and the average response time have been estimated in terms of the data file size. Discussion is also provided on an effective shuffling algorithm to determine the dispersed location sites. Finally, this paper describes a prototype system configuration for several practical network applications, including the hybrid utilization of cloud computing facilities and environments which are already commercialized.
