amount of data with Hadoop distributed file system (HDFS) but processing personal or sensitive data on distributed environment demands secure computing. Originally Hadoop was designed without any security model. In this project, security of HDFS is implemented using encryption of file which is to be stored at HDFS. For encryption a real-time encryption algorithm is used. So a user who has the
