Homomorphic Elgamal Encryption in NoSQL for Secure Cloud

Shagufta Praveen

NoSQL adopted by number of leading organizations. RDBMS doesn’t fit with today’s Big Data scenario. Rapid growths of data not only ask for storage but ask for its security too. This paper provides the specific method to secure data on cloud with the help of Homophormic Elgamal Encryption (HEE). To implement our work, column oriented database (HBase), an awesome storage explanation for NoSQL database is chosen. Data encrypted using proposed HEE scheme, using Microsoft Azure toolkit and basic .NET package with SQL server. Thus, only authentic user can access the NoSQL database by following this proposed method. Cause of the proposed functionality, HEE algorithm allows users to send encrypted data, which would compute the cipher text without decrypting it and send back same encrypted effect to a server or user.
