Performance Evaluation of a Disaster Recovery System and Practical Network System Applications

This paper proposes an evaluation result of a high security distribution and rake technology for realizing disaster recovery. In an experimental evaluation, the encryption and spatial scrambling performance and the average response time have been estimated in terms of the file data 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, which will be soon commercialized.
