Abstract

“Big Data” - voluminous and variety of data from different sources, which demands innovative processing and analysis for decision - making analysis. The data can be either in form of structured or unstructured data. Processing big data with the traditional processing tools and the present relational database management systems tends to be a difficult task. Parallel execution environment, like Hadoop is needed for processing voluminous data. For processing the data in a open framework like Hadoop we need a highly secure authentication system for restricting the access to the confidential business data that are processed. In this paper, a novel and a simple authentication model using one time pad algorithm that removes the communication of passwords between the servers is proposed. This model tends to enhance the security in Hadoop environment.
