Security Enhanced to GSI: An Integrated Framework with a Mechanism

This paper presents a framework for GSI to integrate security components from the viewpoint of connection. To enhance security and security of virtual organization, A multi-homed architecture model is given, which employs a mechanism based on modified SOCKSv5 to support the resource utilization for GSI itself. The framework and the modified mechanism is independently. With the mechanism, the GSI can provide dynamic connection through multiple exits in a virtual organization transparently, and the traffic flow can switch smoothly among the multiple proxies by maintaining a coherent connection context. With the cooperation of some other GSI security components, the model and the mechanism enhance the security and performance of GSI to some extent.
