摘　　要：传统供应链平台往往由于中心化的特性导致信息不对称,用户数据容易面临泄露的风险。针对这一问题,提出结合区块链技术对物流供应链信息进行加密解密。区块链技术具有匿名性、去中心化等特点,能够更好的保证物流供应链中用户信息的安全,通过非对称加密以及对称加密混合的方式,并设计相应的环签名算法以及PoA共识机制。经算例验证,以区块链技术为依据的物流供应链信息加密算法相比ECC算法在加密解密的速度上大幅提升,同时CPU占有率更低,加密解密的安全性更高。Traditional supply chain platforms often lead to information asymmetry due to the characteristics of centralization,and user data is easily exposed to the risk of leakage.In view of this problem,it is proposed to encrypt and decrypt logistics supply chain information in combination with blockchain technology.Blockchain technology has the characteristics of anonymity and decentralization,which can better ensure the security of user information in the logistics supply chain.Through the hy-brid of asymmetric encryption and symmetric encryption,the corresponding ring signature algorithm and PoA consensus mechanism are designed.The example verifies that the logistics supply chain infor-mation encryption algorithm based on blockchain technology has a significantly improved encryption and decryption speed compared with the ECC algorithm,and the CPU occupancy rate is lower,and the secu-rity of encryption and decryption is higher.
