SECURITY FOR CLOUD COMPUTING USING MAP REDUCING FRAMEWORK WITH KEY GENERATION TECHNIQUE FOR A HADOOP ENVIRONMENT

Cloud Computing is an emerging technology in today's world. Cloud computing is an efficient technology for storage and retrieval of data in the fastest mode. The main issue in cloud computing is data security. This paper proposes the bigdata technology with the Hadoop Distributed Framework for storing huge data in cloud in ahighly efficient manner. The distributed Environment demands secure computing to access personal or sensitive data, using Hadoop Distributed File System(HDFS). The quick,automatic fault detection. and recovery mechanisms are available in HDFS.In order to avoid third party issues and produce unrelated data to the selective block in the cluster,the study proposes a Hadoop Distributed File System using, key generation techniques for Data Replication to avoid the issues in the Data replica (i.e., copies of distributed files) and corruption data.
