Athens Openstack User Group meeting

You are invited in the third OpenStack meetup in Athens. We will have Nikos Fotiou and Apostolis Machas present their work on security concerns over Swift.

We will have the chance to discuss more the latest developments on the OpenStack project.

See you there!


Topic: Swift & secure data: A lightweight approach

Cloud computing is an appealing paradigm receiving increasing attention from the industry. However, security concerns still impede the widespread adoption of this technology. Most enterprises are particularly worried about the lack of control over their outsourced data since the authentication and authorization systems of Cloud providers are generic and they cannot be easily adapted to the requirements of each individual enterprise. An adaptation process requires the creation of complex protocols, often leading to security problems and “lock-in” conditions. This presentation is about the design of a lightweight solution that overcomes these problems. We have implemented and incorporated this solution in a popular opensource Cloud stack: the OpenStack.We also show that our design has minimal performance impact and we explore its main performance parameters. Our solution eliminates the need for developing complex adaptation protocols, offers data owners the flexibility to switch among Cloud providers, and enhances end-user privacy.
