Dynamic Secure Interconnection for Security Enhancement in Cloud Computing

摘要

Cloud computing brings efficiency improvement on resource utilization and other benefits such as on-demand service provisioning, location independence and ubiquitous access, elastic resource pooling, pay as usage pricing mode, etc. However, it also introduces new security issues because the data management and ownership are separated, and the management is operated on a virtualized platform. In this paper, a novel dynamic secure interconnection (DSI) mechanism is proposed to isolate the cloud computing system into a couple of dynamic virtual trust zones with different security policies implemented for different customers so as to enhance security. Experimental results are presented to demonstrate the feasibility and effectiveness of the DSI mechanism.
