A Cloud Provider-Agnostic Secure Storage Protocol

Over the last years Cloud Computing has been seen as an emerging technology, which has changed the way computing services are delivered. Cloud computing is not a new technology paradigm, but rather introduces a new way of delivering computing services and resources. On top of its potential value and the several advantages it offers, we can foresee a number of drawbacks of cloud computing, in terms of security and privacy issues. In specific, cloud computing raises the level of expertise needed to protect security and privacy of its stakeholders (i.e. organizations and end-users), mainly due to the fact that the massive concentration of computer resources and data could be a more attractive target to malicious users. In this paper, we present a cloud provider-agnostic model for outsourcing both static and dynamic data to third parties, while preserving their confidentiality and integrity. In addition to a detailed presentation of our model, we also depict an evaluation of it, in terms of its capabilities and weaknesses.
