A Robust and Light Weight Authentication Framework for Hadoop File System in Cloud Computing Environment

The advancement of web and mobile technologies results in the rapid augmentation of traditional enterprise data, IoT generated data, social media data which outcomes in peta bytes and exa bytes of structured and un structured data across clusters of servers per day. The storage, processing, analyzing and securing these big data is becoming a serious concern to large and medium enterprises. Hadoop or HDFS is a distributed file system based on cloud for storage and processing of large voluminous amounts of data across clusters of servers. Along with huge potential for dynamism for processing and scalability, HDFS also brought inherent security drawbacks like lack of authentication and authorization of remote user connecting to cluster, missing of encryption of sensitive data at communication, storage and processing levels. These existing drawbacks demands for a robust, light weight security framework for HDFS. In this context, we propose a secure and light weight remote user authentication framework for HDFS, which guarantees all the critical security requirements of a distributed file system.
