Security and Privacy, Journal Year: 2025, Volume and Issue: 8(3)

Published: April 17, 2025

ABSTRACT The agriculture industry has embraced recent technological advancements to ensure sustainable farming methods, increase resource efficiency, and boost productivity. Nonetheless, merging these technologies raised new security concerns, particularly protecting personal data preserving device communication integrity. We propose a lightweight stream cipher address challenges facilitate secure in smart environments. innovation lies the key‐generating block, which utilizes 128‐bit key 64‐bit Initialization Vector (IV) produce an 80‐bit keystream through iterative round functions. This process involves integration of dynamic nonlinear logic module robust state update mechanism, ensuring high entropy resistance against cryptanalytic attacks. In second phase, is initialized feedback shift register (NLFSR), where it undergoes additional transformations using specialized filter output functions generate final encryption keystream. two‐phase design not only ensures but also adapts effectively constraints systems. Comprehensive comparative evaluations demonstrate that proposed outperforms state‐of‐the‐art ciphers multiple benchmarks, such as Grain v1, Grain‐128, Trivium, Logic. suggested achieves higher throughput, ideal Shannon values, faster decryption times. It exhibits robustness with near‐zero correlation coefficients, passes all 16 NIST randomness tests, efficient memory usage, low power consumption, strong cryptographic makes solution tailored unique needs
