Improvement of Qualification and Throughput of Hybrid Systems for Electronic Mail Security with Using RC6 – Elgamal – MD5 Encryption Algorithms

Abstract

The Electronic Mail is considered one of the greatest applications of communications  and information in this epoch, where the scientific studies  proved that the people now use E-Mail application more than other communication applications because it allows them to send and receive messages with a high speed, easy to use, and save money.  

        Because of this importance for the E-mail we have to adopt necessary steps to protect the information transferred with these electronic messages which may be very important, one of these steps is using Encryption .

         In this paper, we have performed a comparison study to evaluate the performance and efficiency of  many encryption algorithms used to design a general security scheme of hybrid encryption systems which achieve a secure transfer for E-Mail messages across the internet.

        This study demonstrates that RC6-Elgamal-MD5 encryption algorithms have a good performance and high efficiency which help to improve qualification and throughput of this system, so we have used  these algorithms to design and program a hybrid system for E-mail security, finally we used our designed system to get the test values, and we discussed the results .

         We have used  Net Beans  IDE 6.9.1 software to design a graphical user interface of sender and receiver in our designed system to perform the tests and get the results.
