Cloud computing is the domain that provides data storage, data control, and data access, irrespective of software and hardware. Many organizations are updated their storage capacity to store and process the data using several algorithms. Data protection in cloud computing is the primary factoring that protects the data from various attackers. Many solutions are introduced to provide security for the data stored in the cloud; accessing the data with the encryption key offers better protection for the cloud data. Another issue identified in cloud computing is load balancing. If the user requests are more than the threshold value, the load balancing issue occurs in this scenario. This paper describes an advanced key based cloud security (AKBCS) introduced to store and secures the data in cloud storage using three-way security systems. RSA encryption and decryption algorithm used to secure data and large files. Compared with other security algorithms, RSA is the most powerful algorithm that processes large data files in cloud storage.
