Now A Days cloud computing become an extensive area of research where data and resource are sharing among the various user through public cloud .However protecting data and resources on cloud is a challenging issue. In the previous HDFS approach when HDFS file system need to secure this is create additional complicity of algorithm. To address thi s issue and ensuring data security in cloud storage we propose “MESCD” (Multi Level Encryption approach to secure cloud data) has been proposed. In this work file is uploaded and encrypt using N level of different keys further keys are merged into an singl e key ‘K' which is again secure. Decryption processes is reverse of encryption where key (K) is spited into keys ‘N' which is applied to decryption algorithm. The proposed algorithm is effective and efficient then previous HDFS approach.
