This paper proposes, compares and analyses query optimization techniques to securely query encrypted databases. Such querying capability is becoming increasingly relevant as individuals and enterprises move their data to the cloud. The schemes discussed delve into various design issues like speed, scalability and efficiency that are encountered in the context querying encrypted data that is on the cloud. We determine the exact differences in terms of the nature, scenario and behavior amongst the different approaches in between the existing probable solution and our solution that can be applied to the querying problem.
