Abstract: Security threats in the processes of data migration has increased than ever before with the development of cloud computing. Traditionally, device-centric security systems are not efficient enough because a large number of data resources float in the cloud and are out of the owner's control. The security requirements of telecommunications services based on cloud computing comprise three aspects: data storage, data processing, and data transmission. Therefore, this study aimed to design a novel data-centric security protection system. A security model based on the security domain division was proposed. That is to say, the security protection measures were carried out from three data domains: storage, processing, and transmission. The analyses indicated that the novel model could not only provide dynamic and differentiated protection but also be implemented at a lower cost for telecommunications services in cloud computing.
