Data security management of logistics network based on blockchain technology

The logistics network is composed of lines and nodes. The traditional logistics is too centralized, so it is necessary to try “decentralization” to reduce the management difficulty and operational risk. This paper proposes a security data management method based on blockchain to manage distributed logistics network system. Through IOT technology, the warehouse will be connected by tagging individual items and operating hardware to improve the transparency and localization of all assets. The client of IOT node encrypts the logistics transaction data and uploads it to the blockchain to ensure the privacy and unforgeability of the logistics information, so that the encrypted data can be decrypted by the system nodes and uploaded to the blockchain through the logistics network. According to the experiment of school enterprise cooperation enterprise, this is a sharing framework with high security and high availability.
