Detailed analysis
An important part of the gLite data management scheme is the provision for securely storing encrypted data. These security requirements have been given by the Biomedical research communities in conjunction with the various national and international regulations. This community typically functions with a far lower volume of data than the High Energy Physics collaborations. Therefore, the encrypted data storage has been designed with security rather than data throughput in mind.
The Encrypted Data Storage system is comprised of: Hydra, the encryption key storage and retrieval system; one or more metadata catalogues such as the gLite LFC; a set of clients to communicate with any GFAL-enabled storage element such as DPM. A more specific area that will be covered is the DPM component, which enables grid access to image stores implementing the medical standard DICOM interface. From the experience of the pilot services, we will describe areas of work and performance results of this system.
Impact
The data storage requests of the Biomedical community, that require data confidentiality, have been fulfilled by this system. The Hydra/EDS has been incoroporated into the Medical Data Management system and provides the critical functionalities required. The pilot service provides us with the operational experience and in return we we respond to issues and bugs forwarded from this service.
Conclusions and Future Work
The Hydra/EDS service is a useful way to securely store data on a Grid. This service has been mainly aimed towards the Biomed community but can be generalized to other Grid communities. The future work for the Hydra/EDS service will be driven by the needs of communities that take up or test the service.
