The rapid growth in the availability and popularity of cloud services allows on demand remote storage and the computation. Security and the privacy are the main concern to establish the trust cloud service; a solution is needed to achieve confidentiality and integrity of the user data. Many modern cryptographic techniques are available to protect the user’s data in the cloud storage. In this research, we proposed an asymmetric cryptographic technique for securing the data which encrypts the original message before placing it in the cloud storage. The proposed algorithm is providing the following securities: security in transit and security at rest. Our proposed protocol equipped with the security parameters like confidentiality, authentication.
