Blockchain-Based Autonomous Authentication and Integrity for Internet of Battlefield Things in C3I System

In the Internet of Battlefield Things (IoBT), users and sensor-equipped entities send multiple messages to Command Control Center (CCC) over network. The authentication integrity these are crucial because if an adversary or malicious node transmits, alters, replays messages, consequences will be disasters. Current centralized systems not suitable for distributed environment such schemes prone a single point failure, privacy, scalability issues. Moreover, high communication overhead caused by centralization increases energy consumption. this work, we propose technique called Blockchain-based Autonomous Authentication Integrity (BIoBT) C3I system. proposed does require explicit channel it is performed on blockchain side when receiving data. addition, provides data non-repudiation. BIoBT prototype created, deployed, tested Ethereum test results prove that efficient, cost-effective, satisfies security requirements IoBT. also outperforms contemporary mechanisms in terms number required establish secure channel, thereby reducing resource
