Comparative Study On Encryption Algorithms And Proposing A Data Management Structure

Abstract In implementing a web-based application security is one of the most important issues to be addressed. Generally two factors should be addressed prior to implementing the application to ensure security the structure of data management and data security strategy. In this research we try to find a suitable implementation and solution to handle these two problems. These issues first led us to perform a comparative study on several encryption algorithms and consequently to find the most suitable one and second to find the best management structure of data to ensure a reasonable level of security for the clients of the web-based application. We study and compare the concepts of five encryption algorithms that are most widely used DES Triple DES RSA Blowfish and AES. The focus is on the general strategy the encryption algorithms are using and their implementation applicability on websites or web-based applications. A survey was also conducted in finding the level of awareness and concern regarding online systems security. Based on the findings of this study a data management structure for storing confidential data on a server is proposed.
