Title: "Encryption Aware Query Processing for Data Outsourcing"

by

Mr. Javad GHAREH CHAMANI


Abstract:

Outsourcing data to the cloud provides savings in costs and guarantees of 
availability. However, privacy and confidentiality issues often discourage 
owners from outsourcing their data. Although there exist fully implemented 
systems for encrypted database outsourcing, such as CryptDB and SDB, their 
increased leakage and restricted functionality have limited their use in 
practice. One of the most important challenges in these systems is their 
inability to search and perform algebraic operations (e.g., addition and 
comparison) directly on encrypted data. On the other hand, general-purpose 
solutions such as fully homomorphic encryption and oblivious RAM can 
support arbitrary functionalities without any leakage but their poor 
performance prevents their deployment in practice. In this literature 
review, we define and explain the model of interaction and security for 
computing over encrypted data in the cloud setting. We review the most 
important research directions and approaches in the area. We note that 
solutions can be categorized according to three different aspects: 
functionality, privacy, and efficiency. Additional guarantees may include 
outsourced data integrity, access control policies, and different data 
outsourcing architectures. For each type of solution, we attempt to 
identify their strengths and limitations. Finally, we propose some general 
directions for future research, based on the identified limitations.
