Abstract: In recent times, cloud computing has become a trend among many organizations to store and retrieve data across the globe. In this data storage devices and data retrieval process, security is the prime concern to the client. This task provides a challenge to the service providers in terms of security and consistency. As shared systems are prone to be attacked, various counter measures have been proposed by experts to secure the stored data. In this research, yet another efficient technique is introduced to the storage and retrieval process, the data is encrypted by the advanced Encryption algorithm with AES-X encryption which is considered to be the most competent in the present security scenario. The main aim of this study is to throw light on how to store massive data in small space. In order to use AEX-X encryption, the number of rounds of AES algorithm should be increased. A symmetric key is generated to the stored file. To further enhance the trust of the service provider, the trust certificate of the company is sent along with the keys to the client. A hash function is also generated to enhance the security of the stored file. Also, the trust of the service provider is provided to the client by sending the trust certificate of the company along with the keys to the client. All the communication process is taken place using the DH key exchange protocol. These techniques are performed to ensure the client that the stored data is secured, integrated and a total control over the route in which the data is communicated. In this research work, a new efficient technique is proposed which indicates the effectiveness, flexibility of the storage and retrieval process by a generic framework. This framework fills the gap between the security needs and challenges.
