Description

Data management is essential to large scale distributed systems. They are becoming very popular, especially with Cloud Systems becoming more and more widespread and online services such as the Amazon EC2. In this context there are however a number of difficult challenges which must be overcome. One of these challenges is security. A data management system must offer an adequate level of security, thus making sure that the data is stored safely and that only the owners have access to it. In this thesis we propose a novel system to improve the security of distributed data management systems. Our solution offers certificate management, encryption capabilities, as well as credential management. Using these mechanisms we enable authentication, authorization and secure data transfer. The proposed solution was integrated into BlobSeer, which offers high performance for data transfer and efficient data management. We tested our solution, proving that it handles all the security tasks very efficiently, either with the AES or DES encryption algorithm, without adding any significant overhead to the data management system, thus preserving the overall performance of the system.
