Abstract: Now-a-days, the excessive use of internet cloud has received much attention. Cloud computing is the evolving paradigm that provides the services in which cloud consumers can remotely store their data into the cloud and access the on-demand high-quality applications. Cloud computing is mainly used for resource sharing and with very low-maintenance. In the existing Extendable Access Control System procedure, the authority is the trusted party, but in many cases, they may perform an illegal action which leads to data loss. In the proposed work encryption of data is done through Uncrackable Cipher Dynamic Double Encryption Standard (UCDDES). UCDDES performs with the key length of 32, 40 and 48. After dynamically selecting the key length the data governor sent the key request to the authority. Then the data governor generates the partial secret key based on the obtained key length. It is further used to decrypt the data and store in the cloud. As a result, the security of cloud and access control are improved and the problems faced by the unauthorized user/ hackers accessing data are reduced. It also increased the cloud security and prevented from dictionary attacks, brute force attacks, collision attacks, and so on.
