Abstract:

Cloud computing is an emerging computing technology that enables users to distantly store their data into a cloud so as to enjoy scalable services when required. Privacy and Security are thus important issues in cloud computing. The secured structure was proposed to upgrade centralized approach to decentralized access control. In the proposed scheme, the cloud verifies the authenticity of the user without knowing the user’s identity before storing data. Attribute based access control has provided in which only valid users who have matching attributes are able to decrypt the stored information in cloud. The two protocols namely attribute based encryption and attribute based signature are applied to achieve authenticated access control without disclosing the identity of the user to the cloud. This scheme prevents illegal attacks and supports design, alteration, and reading data stored in cloud. This scheme also addresses user revocation. The added feature is the access policy of record can be hided from the cloud. Moreover, authentication and access control scheme is decentralized.
