We recommend a secure cloud-based application forenhancing revocable attribute-based encryption technique. In addition to this to rise the security of the document we designed a modified AES algorithm along with some pre-encryption modifications in document to make system more safe and adept. In our paper firstoff all,there is outline for the makingof a revocable attribute-based encryption (RABE) schemehaving some modification in existing RABE algorithmin conjunction with the characteristics of ciphertext relegation by fewefforts and exclusively combining some techniques to roll back the computation overhead. Then there is not only the presentation of fine-grained access control but thedata sharing mechanism for on-demand services along with dynamic user groups in the cloud. There is comparison between existing and our proposed methodology in our proposedtechnique. Particularly, in this paper the main focused on upgraded RABE scheme that plays avaluable role in cloud-basedapplication. Furthermore, in thisuser revocation there is new concept of adding and deleting of users. The comparative data proves that our proposed innovation is more effective and scalable than existing one.
