<abstract>Nowadays two layer encryption is the process of enforcing fine-grained access control to the cloud. Sensitive information or secret data transferring in to the cloud by using encryption is an important concept. Under this scenario, data owners encrypt the data to the cloud before uploading them and whenever user credential changes, then reencrypting encryption process takes place. Users register to the data owners and data owners are sending the secret keys of registered users. Data owner is communicating with clouds and users. For this, the authors have proposed an approach known as multi layer encryption, which is used to reduce burden of the overhead work at the data owners. So, in this process, the authors use multi layer encryption approach, whereas the data owners perform a coarse-grained and cloud performs a fine-grained encryption. The authors analyzed this process by using KeyGen algorithm and Attribute Based Group Key Management algorithm.</abstract>
