摘　　要：为提升供应链的安全性和透明度,本文设计了一款基于Paillier同态加密算法的数字化供应链溯源方案。数据显示,文件数量为1600时,基于Paillier同态加密算法的密文检索方案的检索时间为0.6×10^(3)ms,明显低于灵活多关键字搜索方案。在数字化供应链溯源系统测试中,当查询次数为1000时,系统每秒事物处理量为979,平均响应时间为0.62s。结果表明,系统在查询和上链测试中表现较好,吞吐量和响应时间均达到较高水平。基于Paillier同态加密算法的数字化供应链溯源方案具有良好的安全性和效率,可以有效实现对供应链的全面控制。To enhance the security and transparency of the supply chain,a digital supply chain traceability solution is proposed based on Paillier homomorphic encryption algorithm.The data shows that when the number of files is 1600,the retrieval time of the ciphertext retrieval solution based on Paillier homomorphic encryption algorithm is 0.6×10^(3)ms,significantly lower than the flexible multi keyword search solution.In the testing of the digital supply chain traceability system,when the number of queries is 1000,the system has a processing capacity of 979 transactions per second and an average response time of 0.62 seconds.The results indicate that the system performs well in query and on chain testing,with high levels of throughput and response time.The digital supply chain traceability solution based on Paillier homomorphic encryption algorithm has good security and efficiency and can effectively achieve comprehensive control of the supply chain.
