摘　　要：基于工业互联网的物流供应链管理技术,业界聚焦在高精度数据分析算法的应用,对数据隐私保护算法的应用目前还处于起步阶段。然而,交易、支付环境不可信,数据易丢失及溯源难等问题,较大程度地制约了物流供应链管理技术的进一步发展。为简化过程,以物流价值链为例,将区块链技术应用于物流场景中,通过数字签名、非对称加密和Merkle树等算法,保障了商品数据的完整性和机密性,提供了物流订单数据溯源功能。最后,相比于业界类似技术的安全性,该方法更能满足实际工程应用对安全目标的需求,为后续落地实施提供了有力的技术支持。Based on the industrial Internet logistics supply chain management technology,the industry focuses on the application of high-precision data analysis algorithm,the application of data privacy protection algorithm is still in the initial stage.However,problems such as unreliable transaction and payment environment,easy loss of data and difficulty in tracing the source restrict the further development of logistics supply chain management technology to a large extent.To simplify the process,we took the logistics value chain as an example and aimed to apply the blockchain technology to the logistics scene.Through algorithms such as digital signatures,asymmetric encryption and Merkle trees,our technology not only guaranteed the integrity and confidentiality of product data,but also the traceability function of logistics order data was provided.Finally,compared with the similar technologies in the industry,our method can better meet the security objectives of practical engineering applications,and provide strong technical support for subsequent implementation.
