Abstract
V originále
In this paper, we propose an architecture that extends Logistical Networking to use Grid authentication and authorization services. Our architecture guarantees that user is authenticated to all services included in network storage stack, the authorization granularity is also at the service level and all authorizations can be revoked at any moment by service providers. We also support access policies. These can limit maximum amount of distributed storage space allocated to a user or group of users or they can limit the maximum amount of time the client can keep his data within the distributed storage. Advanced access control to files is supported, administrators can define access conditions. The prototype implementation has been used to evaluate overhead associated with the security enhancement. This overhead is negligible for Auth, Allocate, Load, and Store commands if only capabilities are encrypted, the Copy command has a penalty of some 10ms (rather negligible for large data transfers). When full data encryption is enforced, the Load, Store, and Copy command are bound by the speed of the used AES 128 cipher.
