Abstract

—With the increasing use of technologies today across the globe and an increase in data breaches over chat applications, the concern over security has grown into a significant problem. Technology advancements and growth in data flow rates are making it more challenging to protect user data since they are more susceptible to cyber-attacks. This brings in the need for a secure communication system for the smooth streamlining of emerging technologies. Blockchain technology and cryptography are currently the two most important security principles. By combining both, the goal is to offer a double layer of security through the use of asymmetric key algorithms, hash functions, and digital signatures, which ensure the process’s integrity. The entire communication system is a hybrid of blockchain and cryptography. The aim is to advance security by offering a blockchain-based secure communications solution.
