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 that cannot break by the high computing like quantum computer. 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.

Quantum key distribution (QKD) is one of the secure ways of distributing the keys among entities involved in communication. BB84 is the first protocol for QKD in year 1984. In this paper we are simulated a new proposed way to enhance quantum key distribution protocol BB84 by employ the basis of original BB84 protocol, so that both parties can negotiate a shared secret key without using the classical channel and hence without loss any information. Finally, the experimental outcome confirms that the proposed protocol delivers efficient results comparing with the original BB84 protocol.
