A Survey on Secure Cloud: Security and Privacy in Cloud Computing
Shyam Nandan Kumar, Amit Vajpayee · American Journal of Systems and Software · 2016
Cloud computing is an emerging technology that is still unclear to many security problems. The security problem becomes amplified under the cloud model as new dimensions enter into the problem scope related to the architecture, multi-tenancy, layer dependency, and elasticity. This survey paper introduces a detailed analysis of the cloud security problem. In this paper various existing approaches related to data encryption and message authentications are discussed. After study the existing approaches, issues and challenges are point out during data processing over the cloud. Instead of only encryption or authentication, this paper suggests attribute based encryption and attribute based authentication together, during communication over the cloud for achieving better security.
