A Blockchain Trusted Mechanism (BTM) for Internet of Unmanned Things (IoUT) Using Comprehensive and Adaptive Schemes

The intelligent decision-making and communication among devices, allowing direct transmission among various entities and human, is the key component of Internet of Unmanned Things (IoUT). By gathering various smart devices (SDs) into clusters (Cls), the SDs within one cluster may share the information and deter malicious devices from network access by modifying and accessing the controls. The security of SDs can be provided through various security frameworks and mechanisms with and without blockchain. However, the SDs are not fully secured by spreading fake information and text alterations in the network. In this paper, we have proposed a secure and trusted communication mechanism using blockchain-based adaptive and comprehensive trust computation of each DS. The proposed mechanism ensures significant security and trust even with various malicious involvements. The simulation results are further demonstrated against various mechanisms such as probability attack, accuracy and communication delay in comparison of existing approach.
