Secure Authentication and Access System for Cloud Computing Auditing Services Using Associated Digital Certificate

Cloud computing helps in transforming the traditional internet computing paradigm and IT industry. Since many Cloud Service Providers (CSPs) are untrusted, the confidentiality, integrity, and privacy of the enterprise information must be protected by some mechanisms. In this paper, we proposed a new framework to enhance secure data storage, fine grained access and preserve data from unknown users or intruders in enterprise cloud. In the proposed mechanism data is encrypted under the set of user attributes and privilege access rights. The Associated Digital Certificate (ADC) is generated for secure, authenticated and fine grained access from cloud. The proposed framework extended the research towards user revocation and integrity check by data owner. Thus, the analysis of our newly approached scheme is provably secure and efficient in enterprise cloud than other existing scheme.
