Exploring a New Security Framework for Cloud Storage Using Capabilities

We are seeing the deployment of new types of networks such as sensor networks for environmental and infrastructural monitoring, social networks such as facebook, and e-Health networks for patient monitoring. These networks are producing large amounts of data that need to be stored, processed and analysed. Cloud technology is being used to meet these challenges. However, a key issue is how to provide security for data stored in the Cloud. This paper addresses this issue in two ways. It first proposes a new security framework for Cloud security which deals with all the major system entities. Secondly, it introduces a Capability ID system based on modified IPv6 addressing which can be used to implement a security framework for Cloud storage. The paper then shows how these techniques are being used to build an e-Health system for patient monitoring.
