Enhancing Blowfish Cryptography Technique for Cassandra
Subscribe/Renew Journal
The popularity of Cassandra has been increasing day by day. Cassandra is a database management system designed to handle very large amounts of data spread out across many servers. Cassandra is used by number of companies such as Twitter, Mahalo, Facebook etc, to construct their Projects. Nodes on a peer –to- peer architecture can communicate freely and no authentication or encryption is provided. As increasingly sensitive data is being stored in Cassandra databases, hence database management and security issues are important and become growing concerns. This paper gives an overview of Cassandra and its features, the cryptography techniques RSA and Blowfish and ongoing research to monitor performance of Cassandra with encryption techniques. This survey analysis the performance of Cassandra when two encryption techniques RSA and Blowfish are used.
