There are many different techniques that have been developed to improve security of confidentiality of the user's data in the cloud storage. The assurance of confidentiality of the data stored in cloud storage and the exchange of data and sharing a key that is used to encrypt the data between two parties has been a major concern in the recent years due to the increased use of the cloud services. Also, to more security, we need to store the key away from the cloud and need data encryption in way

In this paper, we proposed a system that encrypts client's data by an encryption algorithm, by using a key that is generated from Enhancement BB84 protocol, the data can be decoded only with the authenticated user that grants the key from Quantum Key Distribution Server (QKDS) over quantum channel and decrypts the data uploaded to the cloud. The simulation results show that our proposed system was effective in producing more security and less time in the process of data encryption and it provides a security for confidentiality of the user's data in the cloud.
