Cloud-Oriented IoT: Distributed Power-Aware Security Scheme with Data Integrity and Performance Enhancement

The accelerated growth of IoT devices creates new problems about protecting data while assuring ethical standards and reducing power requirements. The authors present DPASS as a security scheme that unites SDN and blockchain technology to secure IoT networks and simultaneously reduce power consumption. The Energy-Aware Secure Chain algorithm within the proposed framework combines three operational mechanisms including the FEP for quick node-validation and SZPM for minimal-resource data transmission and Secured Spatial Storage and Query for secure data integrity. The system leverages IBM Watson IoT and Ethereum blockchain for implementation and evaluation. The proposed model exhibits superior results compared to existing products regarding both execution speed and authentication strength with better computational capability and power efficiency metrics. The experimental results show that DPASS establishes strong network security without wasting excessive resources thus providing an excellent solution for secure IoT deployment. The research achieves architectural advancement for robust IoT systems through a combination of SDN-based automation with blockchain’s unalterable security elements which ensures reliable device connectivity.
