Abstract
Current e-commerce transaction encryption and secure logistics sharing methods, despite using advanced data encryption, still face risks of data leaks and payment security vulnerabilities, sometimes due to weaknesses in network protocols. To address these challenges, this study introduces a blockchain-based approach combined with the RSA asymmetric encryption algorithm, which enables secure decryption without direct key transmission. Experimental results demonstrate that the proposed solution significantly reduces the communication overhead compared to that of existing dual-layer consensus and IoT-based architectures. With 40 nodes, it achieves just 302 transactions of overhead at 50 TPS and a minimal system memory usage of 0.502% at 40 TPS. Furthermore, at a high throughput of 120 TPS, the algorithm completes transactions in only 53.47 ms—far faster than competing methods. These improvements enhance both security and efficiency, offering a more reliable framework for e-commerce transactions and logistics data sharing while strengthening trust in digital trade.
