Chat Application Using Homomorphic Encryption

Abstract

Chat applications nowadays have evolved into one of the most significant and widely used applications on smart devices. They are capable of sending and receiving messages, documents, and images with zero cost to any part of the world. All the messages should be protected. All the chat applications today are used to send messages quickly and securely. The actuality of the situation is that the messages sent are not as secure as they claim to be. So, to bridge this gap, in this paper Homomorphic Encryption is used to secure the messages further while also not reducing the speed of the transaction. This paper aims to implement a Chat application using Homomorphic Encryption which adds a layer of security over end-to-end encryption.
