Blockchain and 6G: The Future of Secure and Ubiquitous Communication
This work addresses the problem of designing secure and efficient communication systems for future applications like 6G networks, but it is incremental as it categorizes existing requirements without introducing new methods.
The paper tackles the challenge of meeting performance and security requirements for future communication systems by proposing the combination of blockchain and 6G to address data rates, latency, reliability, and security needs like integrity and auditability, resulting in a framework that facilitates secure and ubiquitous connectivity.
The future communication will be characterized by ubiquitous connectivity and security. These features will be essential requirements for the efficient functioning of the futuristic applications. In this paper, in order to highlight the impact of blockchain and 6G on the future communication systems, we categorize these application requirements into two broad groups. In the first category, called Requirement Group I \mbox{(RG-I)}, we include the performance-related needs on data rates, latency, reliability and massive connectivity, while in the second category, called Requirement Group II \mbox{(RG-II)}, we include the security-related needs on data integrity, non-repudiability, and auditability. With blockchain and 6G, the network decentralization and resource sharing would minimize resource under-utilization thereby facilitating RG-I targets. Furthermore, through appropriate selection of blockchain type and consensus algorithms, RG-II needs of 6G applications can also be readily addressed. Through this study, the combination of blockchain and 6G emerges as an elegant solution for secure and ubiquitous future communication.
