Design of a Blockchain based Data Security Guarantee System for Logistics Systems

The modern logistics industry is facing significant data security challenges. The decentralized and transparent nature of blockchain technology provides a solution strategy. This study designed a logistics system based on the blockchain. In addition, a data security guarantee system was constructed, and the performance was tested. This study used a probability output regression algorithm. The system delay increased from 220 ms to 420 ms when the number of nodes was increased to 110. On the other hand, the PoR algorithm that introduces the reputation mechanism exhibited a lower initial delay (143). Moreover, when the number of nodes was increased to 110, its delay decreased by 90 ms compared to the PoR. When the number of nodes was increased to 60, the throughput of the PoR exceeded that of the reputation mechanism. The performance test of logistics data sharing showed that the processing time dimension was dataintensive, with a distribution density of 0.68. During the data-sharing process, 2350ms is required for every thousand encryptions; 3154 ms and 4263 ms were required for re-encryption conversion and decryption, respectively. This system performed well in terms of performance and data security, effectively handling large-scale logistics data, reducing the system latency, improving throughput, and ensuring data security. This result has profound significance in promoting the digital transformation of the logistics industry, improving operational efficiency and service quality.
