Integration of IoT and Blockchain for user Authentication

Abstract

The proliferation of Internet of Things (IoT) devices has ushered in a new era of connectivity, necessitating robust solutions for user authentication to address security and trust challenges. This paper explores an innovative approach to user authentication in IoT environments by leveraging the unique capabilities of Non-Fungible Tokens (NFTs) and 9NM (9NFTMANIA) tokens, with a specific focus on utilizing contract addresses. The proposed system involves the tokenization of user identities through the creation of contract addresses on blockchain networks. Each user is assigned a unique digital identity represented by an NFT or 9NM token, providing a tamper-proof association between the user and their cryptographic keys. Blockchain smart contracts are employed to manage authentication processes, dictating access control policies based on the user's contract address. The research underscores the importance of industry-wide collaboration to develop common standards for user authentication in IoT environments. By offering a comprehensive exploration of user authentication in IoT using contract address-based NFTs and 9NM tokens that are developed on Satoshi core based blockchain, this paper contributes to the advancement of secure and user-centric practices in the rapidly evolving landscape of IoT technology. The proposed framework not only enhances the overall security posture of IoT networks but also lays the foundation for a more transparent and interoperable authentication ecosystem. This paper has discussed the mechanism where web 3.0 based programming is made using Javascript, Python, ASP.NET and PHP for user authentication considering presence of smart contracts in user wallet.
