Abstract: Cloud computing has been developed to deliver information technologies services on demand for organisations or as individual users. In this paper, we describe an approach which proposes a security model bases on organisation role-based access control (ORBAC) and encryption system. This model aims to give users a possibility to control security of their data. In this scheme, a secret key is partitioned using a Galois field GF(22). Our proposal has been aligned with model driven architecture (MDA).
