Abstract:

Data security is core issue of Cloud storage. Presently, Cloud storage physical positions of data are relatively changeless so that the uncertainty and complexity of system are low. According to the idea of dynamic resiliency for security defense, as long as the dynamic change is introduced, the security of Cloud storage might be enhanced systematically. Be derived from the idea, a novel mechanism, named dynamic cloud security storage system based on data drifting, is presented. The mechanism firstly separates a document into particles, and then stores them on different nodes of Cloud storage. The particles are driven to keep drifting among nodes during the store, to achieve the dynamic resilient storage view. Once user needs the document, all of the particles are gathered to the nearest node for following download. In order to improve the security, uniform distribution and Mason rotation method are mixed together to obtain better randomness. For the effective utilization of the idle network bandwidth, without affecting normal network data communication, the instance also adds a traffic monitoring module by actively drift traffic control. The simulations of the system with respect to the mechanism show that it has valid functions and security.
