区块链技术及其在物流信息中的应用

区块链技术及其在物流信息中的应用(任务书,开题报告,论文说明书16000字)
摘  要
大数据潮流的到来使现代物流信息数据容易成为网络攻击的目标，现代物流信息技术易遭遇信息泄露的危机，成为不法分子攻击的载体。区块链具备去中心化、去信任化、匿名化、安全可靠、可扩展的特点，能够保障共享经济平台上用户信息的真实可靠，建立用户之间的信任关系。
本文以电商交易环境下的用户信息泄露为背景，依托区块链技术设计了一个保障用户信息安全的新型网络购物平台，最终达到保障顾客个人信息、交易信息、支付信息的安全，确保了最后物流配送环节可溯源。
本文主要研究内容包括：综述国内外区块链技术的研究现状，结合国内外学者提出的相关理论成果，阐述了区块链技术的发展与作用。参考目前金融业、信息产业中区块链技术的应用，着重分析了区块链中哈希算法、merkle tree、共识机制、非对称密钥以及对等网络等核心技术。在深度剖析传统电商存在的安全问题后，针对新型网购平台的需求进行分析，对区块链技术下的网购平台进行了模块划分，有效的将区块链技术与顾客注册、双方交易、支付行为和物流配送四个环节结合。在此基础上，创建了基于Hyperledger Fabric的多节点区块链，并在所创建的区块链上实现了简单的功能。最后，本文总结了基于区块链技术的网络购物平台的优势与不足。

Abstract
The arrival of large data age makes modern logistics information data easy to become the target of network attack. Modern logistics information technology is easy to be exposed to the risk of information disclosure and become the carrier of sustainable attack. The block chain has the characteristics of decentralization, trust, anonymity, safe, reliable and scalable, and can guarantee the trustworthiness of user information on the shared economic platform and establish the trust relationship between users.
Based on the leakage of user information in the environment of electric business transaction, this thesis designs a new type of online shopping platform which protects users 'information security, and finally guarantees the security of customers' personal information, transaction information and payment information. Logistics distribution links traceable.

The main contents of this thesis are as follows: The research status of block chain technology at home and abroad is reviewed, and the development and function of block chain technology are expounded according to the relevant theoretical achievements put forward by domestic and foreign scholars. In this thesis, the core technology of the hash algorithm, merkle tree, consensus mechanism, asymmetric key and peer - to - peer network in the block chain are analyzed emphatically, referring to the application of the block - chain technology in the financial industry and information industry. After analyzing the security problems of the traditional electrician in depth, the paper analyzes the demand of the new online shopping platform, carries on the module division to the block purchase technology under the block chain technology, effectively carries out the block chain technology with the customer registration, the two sides transaction, the payment Behavior and logistics and distribution of four links. On this basis, combined with the merkle tree java implementation, created a multi-node block based on Hyperledger Fabric chain, and created in the block chain to achieve a simple function. Finally, this thesis summarizes the advantages and disadvantages of the network shopping platform based on the block chain technology.

The results show that compared with the traditional online shopping platform, the use of block chain related technology to build the online shopping platform can effectively protect the user's privacy and security.
The characteristics of this thesis are: the block chain related technology applied to four consecutive but different scenes, compared with the traditional online shopping platform, fully demonstrated the advantages of the block chain.
Keywords: online shopping; block chain; encryption
