Cloud computing multi-tenancy feature, which provides privacy, security and access control challenges, because of sharing of physical resources among untrusted tenants. In order to achieve safe storage, policy based file access control, policy based file assured deletion and policy based renewal of a file stored in a cloud environment, a suitable encryption technique with key management should be applied before outsourcing the data. In this paper, a decentralized access control scheme is proposed for secure cloud storage by providing access to the files with the policy based file access using Attribute Based Encryption (ABE) scheme.
