Privacy and security of smart irrigation data using IOTA distributed ledger

Abstract

IoT-enabled smart agriculture enhances farming with real-time data insights but faces security and scalability challenges. This study integrates IOTA’s distributed ledger technology into smart irrigation systems, leveraging its Tangle architecture for fee-less, lightweight, and scalable transactions. The system ensures tamper-proof data integrity and real-time decision-making, crucial for precision agriculture. Experimental results show efficient data transmission (336 bytes) with processing times of 0.7–1.3 seconds and rapid data retrieval (1×10⁻⁶– 4×10⁻⁶ seconds). A comparative analysis highlights IOTA’s superiority over traditional blockchain systems, demonstrating its robustness, scalability, and efficiency for secure, real-time IoT-based smart farming.
