Analysis on Computational Time of Hybrid Cryptography in Email System

Abstract

E-mail is one of the most prominent, fastest and low-cost means of communication. Millions of people have made E-mail as a part of everyday life where it changes the way of work and collaboration as the E-mail messages can be sent to an individual or groups. However, the inherent vulnerability of the E-mail system can cause immense risks of information disclosure and misuse. The common threats to the E-mail system are malicious threats whether it is a malware attachment or a URL leading to malware, phishing or exploitation, spam, spoofing and unauthorized access. The aim of this project is to enhance the E-mail security system from being attacked by threats. This paper had proposed to use modified AES and RSA hybrid algorithms to increase the E-mail security system. Time execution of the algorithm is taken as the result of this research paper. It can be concluded that by modifying AES bit key to 320-bit, it can increase the E-mail security system.
