DSCoT: A Blockchain Tokenization-enabled Architecture for Digitization and Authentication of Assets in Smart Cities
Usman Khalil presented at the 2022 7th International Conference on Cloud Computing and Internet of Things (CCIOT 2022)
School of Digital Science PhD student Usman Khalil presented his paper, DSCoT: A Blockchain Tokenization-enabled Architecture for Digitization and Authentication of Assets in Smart Cities, at the 2022 7th International Conference on Cloud Computing and Internet of Things (CCIOT 2022) . His paper was presented at the session topic: Data Processing and Protocol Design for AI-Based Wireless Systems.
In this paper, Usman proposed a private blockchain-based architecture, Decentralized Smart City of Things (DSCoT), which utilizes Blockchain tokenization (i.e., Non-fungible tokens-NFTs) for the representation and authentication of user and IoT assets by defining smart device attributes. The proposed architecture ensures the functionality of unique assets representation by deploying smart contracts and further for IoT assets and user authentication.
Ssecurity services such as confidentiality, integrity (using SHA-III one-way encryption), availability, and authorization (CIA) are provided by the mechanism of the proposed architecture. The proposed work is evaluated based on Gas consumption and time complexity and the results are promising.
Functions that applied an innovative approach to query the smart contract for assets’ status in the NFT registry offers no transaction cost (in Ether/Gewi), making the proposed extension efficient in time complexity. The proposed architecture strives to provide a smart city solution that may support robust security features utilizing mechanisms of Blockchain, NFTs, and SHA-III encryption.
