DACD: Delegated Access Control of Data in Cloud computing environment

P.Liyaz, N.Phani Kumar, B.Mahesh

Cloud computing provides a service based on internet for several shared resources and system software across various environment. For secure cloud storage the process of encryption of the data to the users for various needs has been brought by the delegated access control method. Generally storage in public cloud requires high communication, heavy load due to maximum storage and high computational costs. In this paper, we are implementing multi-cloud environment for secure storage where it acts as a public cloud and provides low costs, also it involves two- layer encryption over the data stored in the cloud. We are using an efficient AES algorithm which provides higher confidentiality and privacy for several users in the cloud and stores the data in multi-clouds where the users can retrieve with the keys later while delegating it through access control from the cloud. Security as well asaexpenses are the peak issues in this field of research and they vary significantly, depending on theavendor.
