A secure sharing and exchange method for digital supply chain data based on cloud platform architecture
Most conventional digital supply chain data sharing and exchange methods are designed using the digital twin prin-ciples.In practical applications,data security sharing and exchange has a long latency,poor sharing timeliness,and is prone to data distortion and leakage,reducing the security and reliability of sharing and exchange.In order to improve this issue,research has been conducted on the secure sharing and exchange method of digital supply chain data based on cloud platform architecture.Firstly,establish a digital supply chain data trading center architecture based on cloud platforms,solve data value disputes,im-prove supply chain operational efficiency and efficiency,and ensure orderly operation of data sharing and exchange.Secondly,the digital supply chain data is symmetrically encrypted using a key agreed upon between the data sender and receiver.On this basis,design a data transmission and sharing exchange process,using Kafka as the transmission tool for secure data sharing and exchange in the digital supply chain,to achieve the goal of secure integrated transmission and sharing exchange of data.According to the ex-perimental analysis results,it can be seen that after the application of the proposed secure sharing and exchange method,as the number of data nodes in the digital supply chain increases step by step,the maximum latency of data secure sharing and exchange does not exceed 5ms,and the maximum throughput can reach over 400 bit.It can safely complete data sharing and exchange tasks in a short period of time,improving the security and timeliness of data sharing and exchange.
