Abstract. The enormous data performed within Cloud computing because of its strength to present users among adjustable, safe, on-demand, and low-cost co-operation. Among the rising utilization of cloud applications, data safety assurance has grown an essential point during the cloud. Constructing a Reliable Hadoop essentially a cloud computing is a great difficulty for the cloud. The protection system can be utilized during various services in the cloud such as Platform as a Service (PaaS), Software as a Service(SaaS), and Infrastructure as a Service(IaaS). It also can assist most provisions within Cloud computing. The improvement of the security approach in cloud computing utilizing Okamoto- Uchiyama(OU)Encryption Scheme. In this paper, the proposed method was utilized to enhance the completion of the encryption /Decryption file through utilizing (OU) algorithms combined on Hadoop. Wherever the data are encrypted inside the HDFS and decrypted inside the Map Task. The proposed protection system within cloud computing reached the confidentiality and privacy of the user by utilizing cryptography. The proposed method utilized by the conversion among the system and the cloud’s user.
Implementing the Okamoto-Uchiyama and compared the result with the RSA cryptosystem.
