Enhanced Key Management with Attribute and Access Specification for Data Storage in Cloud Environment

Abstract

Cloud Computing is an emerging technology with a collection of systems provisioning the resources like hardware, software, processing power, network, operating system, storage on pay-you-go basis. Cloud consumers can deploy these resources from various cloud service providers based on their requirements. Storing the users’ sensitive data in cloud is a critical task. Not only securing the data in a proper way is a major concern, but also the access privilege challenges due to the sharing of data stored in cloud is to be considered. The issue of controlling and preventing unauthorized access to data plays a vital role. Thus the access control and permissions on data must be set by the owners of the data based on certain attributes. Hence the proposed system specifies the policy with the given attributes and ensures the access control. This helps in protecting and accessing the data by providing the policy in the key for authenticating and authorizing. The data can be accessed on satisfying the policy and access permissions.
