Critical Controlling for the Network Security and Privacy Based on Blockchain Technology: A Fuzzy DEMATEL Approach

The Internet of Things (IoT) has been considered in various fields the last decade. With increasing number IoT devices community, secure, accessible, and reliable infrastructure for processing storing computed data become necessary. Since traditional security protocols are unsuitable devices, implementation is fraught with privacy challenges. Thus, blockchain technology an effective solution to problems security. Blockchain empirical distribution storage model involving point-to-point transmission, consensus mechanism, asymmetric encryption, smart contract, other computer technologies. Security becoming increasingly important using IoT. Therefore, this study provides a comprehensive framework classifying criteria based on technology. Another goal present identify causal relationship factors issue Fuzzy Decision-Making Trial-and-Evaluation Laboratory (FDEMATEL) approach. In order deal uncertainty human judgment, fuzzy logic tool. study’s results show proposed approach’s efficiency. Authentication (CR6), intrusion detection (CR4), availability (CR5) were also introduced as most essential criteria, respectively.
