On-Chain Key Exchange and Covert communication Via Blockchain smart Contracts

Abstract

There are numerous encryption techniques available to ensure confidentiality and integrity of data. However, encryption alone cannot prevent attackers to exploit vulnerabilities in the implementation of requisite algorithms. Hence, there is always a persistent threat to the security and privacy of data. On the contrary, data concealment techniques hide the existence of communication thus ensuring security through obscurity. Historically, the preservation and protection of data have been achieved using diverse techniques, including timing, storage, and network-based approaches. However, it is important to note that these methods have not been able to ensure comprehensive concealment and security of the data and also were not efficient in terms of embedding capacity, throughput, cost to name few. The blockchain technology presents a viable solution that inherently integrates desirable attributes such as decentralization, anonymity, and immutability within its architectural framework. Despite the limited progress made thus far, it is imperative to modify or introduce novel methodologies to optimize performance, increase embedding capacity, enhance transmission rate, and reduce communication costs, all while concurrently improving throughput. It is feasible to devise and subsequently implement a solution that employs a hybrid approach to address the limitations associated with previously suggested methodologies. The proposed approach utilizes Smart Contracts as its foundation and conducts the entire process on-chain, encompassing key generation and covert information transfer. This method incorporates multiple layers of security measures to enhance the requisite features essential for ensuring secure transmission of covert communication.
