With the continuous development and digital transformation of global logistics business,how to improve the security and credibility of logistics information has become an important issue for logistics enterprises and industries.At present,the traditional logistics information platform has problems such as information islands,lack of trust,and data security cannot be guaranteed.However,blockchain technology is conducive to solving logistics information systems due to its characteristics of decentralization,non-tampering,transparency,security and reliability.Existing problems,so research on the combination of blockchain and logistics,research on the key technologies of the blockchain-based logistics platform and design a blockchain-based logistics platform will help improve the service quality,security,and credibility of the logistics platform is of great significance.This thesis first studies the node authentication technology and logistics document technology of blockchain applied in logistics.On this basis,a logistics platform based on blockchain is designed.The form is stored on the chain,and the whole process is transparent,open and traceable,which is conducive to improving the trustworthiness,traceability and security of logistics information,improving the management efficiency of logistics enterprises and reducing business costs.The main contents are as follows:(1)Research on logistics node authentication technology based on improved ECC.Aiming at issues such as low security and mutual trust of logistics nodes.Using elliptic curve encryption algorithm(elliptic curve cryptography,ECC)combined with blockchain technology to authenticate logistics nodes,ECC has the characteristics of high security,small amount of calculation,and fast processing speed,and can use shorter keys to provide better The security,blockchain distributed storage technology can reduce the dependence on the server,so as to improve the security and credibility of node authentication.In the authentication process,the basic data of the blockchain logistics node user is first uploaded to the blockchain to generate a key pair and a time stamp;secondly,the improved ECC algorithm is used to encrypt the data for transmission;finally,the node is authenticated through signature authentication and timestamp authentication.Authenticate.(2)Logistics documents based on blockchain technology.Aiming at the problems of easy tampering,low data trust,and unguaranteed security in traditional electronic logistics documents,an electronic logistics document solution based on blockchain technology was constructed.By combining the information of logistics transaction activities with blockchain technology,the transaction data in the logistics transaction link is filled into the preset logistics documents,and the blockchain records the required electronic document summaries in the form of transactions.After the time stamp,it is recorded in the node ledger,and at the same time,the access control of the logistics documents is performed using the ciphertext policy attribute encryption scheme,and the customer can log in to the blockchain client to query the corresponding logistics information.(3)Design and implementation of blockchain-based logistics platform.According to the problems existing in the traditional logistics platform,the demand analysis of the logistics platform was carried out,and the overall hierarchical structure of the logistics platform and functional modules such as order,scheduling,business processing,warehousing,customers,and system management were designed according to the requirements and the characteristics of blockchain technology.Apply the ECC-based node authentication scheme to the authentication of blockchain logistics nodes,develop the logistics platform according to the design scheme,and display the business interface of each functional module;and conduct functional and non-functional tests on the logistics platform,and test results It shows that the blockchain-based logistics information platform can meet its normal functional requirements,and the use of blockchain technology can well ensure the reliability and security of logistics data. |
