PROJECT TITLE :

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

ABSTRACT:

The Internet of Battlefield Things (IoBT) allows users and sensor-equipped entities to communicate with the Command Control Center (CCC) via a network. These users and entities send multiple messages. The authenticity and integrity of these messages are of the utmost importance because the consequences will be catastrophic if an adversary or malicious node transmits, modifies, or replays these messages. Authentication is essential. The currently in use centralized authentication systems are not suitable for use in a distributed environment. This is due to the fact that such systems are prone to having a single point of failure, as well as having privacy and scalability issues. Additionally, the high communication overhead that is caused by centralization results in an increase in the amount of energy that is consumed. In this study, we propose a method for the C3I system that we call Blockchain-based Autonomous Authentication and Integrity for the Internet of Battlefield Things (BIoBT). The proposed method does not require an explicit authentication channel for the authentication of entities because it is performed on the blockchain side when receiving the data. This makes the use of an explicit authentication channel unnecessary. In addition to this, it ensures the non-repudiation and integrity of the data. On the Ethereum test network, a prototype of BIoBT is developed, then deployed, and finally tested. The findings demonstrate that BIoBT is effective in terms of both time and money, as well as meeting the stringent standards for data protection imposed by an IoBT distributed environment. BIoBT also outperforms contemporary mechanisms in terms of the number of messages required to establish a secure channel, resulting in a reduction in communication overhead as well as resource consumption.
