Encryption methods on major telecommunication applications and thoughts

Abstract

Ever since the invention and massive implementation of telecommunication invited themselves during wartime, it is crucial to keep the message as secret as possible from adversaries. Back in time, the leak of messages meant thousands of potential casualties whereas now enormous costs on fortune and confidential secrets. In this paper, we will dive into the comparison of modern communication apps such as WhatsApp, Messengers, and WeChat with their encryption methods including AES encryption and RSA encryption. Then, we build a front-to-end message app using the RSA encryption method and an easy version of a random number generator to increase the security level. We will discuss the utility of the three apps and their complexity in terms of the input, algorithm, and pros and cons of the features they provide objectively to the average consumer, regardless of occupation or special personalized need. In addition, throughout the studies of the three apps and their flow of design on how to keep the consumers safe during their sharing of messages, we will discover a trend of evolution in how the society treats the idea of information security and what improvements can be done from time to time.
