Abstract
En 中文
Land is a fundamental resource with significant economic and social value. Land transactions are often carried out by individuals to fulfill their specific needs and requirements that are usually maintained by different governmental offices. However, a land record (LR) generally contains sensitive information associated with the land. In recent decades, the shift from traditional paper-based approaches to digital systems has become increasingly prevalent. Moreover, this transition has brought about certain challenges, including the potential for single-point failures and security vulnerabilities. A blockchain-powered land record management system (LRMS) has the potential to effectively address and resolve the current challenges while maintaining robust security measures. To design a blockchain-based secure LRMS, this paper develops a new lightweight cryptosystem based on a newly proposed hybrid chaotic map that ensures LR privacy. In addition, the paper also proposes a dynamic way of character to integer mapping scheme named the dynamic character to integer (C2I) table that enhances encryption complexity while reducing conversion overhead by approximately 33% compared to the ASCII table. Besides, it streamlines the process of ownership transfer by facilitating a decentralized land trading platform. Moreover, LR integrity is maintained by incorporating both InterPlanetary File System (IPFS) and blockchain as storage. Finally, the experimental results, analyses, and comparisons indicate the effectiveness of the proposed LRMS over the state-of-the-art systems.
