Analysis of encryption algorithms to basic operations on outsourced B+ trees for data privacy

Shared data systems have grown in numbers, many of these are critical in nature. As a recent trend, there has been growing interest in outsourcing database services in both the commercial world and the research community. In the outsourced database service (ODBS) model, clients rely upon the service provider, which include hardware, software and manpower, for the storage, maintenance, and retrieval of their data. Hence, it tends to variety of security challenges involved in it. The outsourced B+ index trees and data are encrypted and stored at some un-trusted server. Here, we discuss implementation of data security issues on outsourced B+ index trees and ensure security in the execution of basic operations like search and updates (insert, delete) on the un-trusted server. Our proposed work aims at presenting the results after implementing basic operations on outsourced B+ index trees with the help of various encryption algorithms to ensure data privacy.
