A Review of Data Confidentiality in Removable Media and Symmetric Key Encryption Algorithms

Abstract

Data confidentiality in any research organization refers to protecting privacy of an individual’s data actively involved in their respective research domains. Data breach can therefore be a big threat to any research organization. Hence it is very important to maintain the confidentiality of data. USB devices provides faster speed for data transmission and are easy to carry at any place, but many research organization denies the usage of removable devices because of security concerns. It is also observed that most of the data theft happens through USB or removable devices as they are more convenient and easy to obtain. In this paper we will analyze different data encryption techniques for removable devices using web based authentication, security tools available for data encryption, performance analysis of various implementations of encryption algorithms, and an efficient data encryption system to compare the execution time and data security with other existing encryption algorithms.
