Blockchain-Enabled 6G Security Architecture for Smart Cities

Abstract

The next 6G technology is expected to change the face of smart cities by offering greater connectivity, faster and higher data transfer rates. A major advantage of using blockchain with 6G networks is the availability of a distributed immutable database to record transactions and data exchange. In the context of smart cities, this feature is very important to ensure the security of data transfer process through many IoT devices and systems. Through implementation of a system in which data cannot be altered or deleted, blockchain increases the credibility and accountability of smart city management. The integration of blockchains with IoT devices especially in the smart cities is therefore helpful. IoT devices which are the foundation for smart cities are prone to cyber threats and malwares. The real-time anomaly detection and the pattern features analysis in machine learning algorithms help to identify the possible risks to safety in no time. Integrated with blockchains, these frameworks help in enhancing intrusion detection, privacy and silence.
