Abstract

With development of e-commerce and intelligent devices, large amounts of asset transaction data and traders’ identity information have been generated. It poses huge challenges to the data security and privacy when data are stored in a centralized trading system. Here, considering the need of data sharing and data privacy in asset trading, we proposed a blockchain-based privacy protecting framework to accommodate both aspects of these requirements. The proposed framework combines a multi-channel access control model and smart contracts to enhance the security and transparency of asset trading within permissioned channels while maintaining privacy for transactions occurring outside of these channels. Furthermore, regarding market efficiency and transaction fairness, we design trading algorithm of double auction to make transaction more automated and intelligent. Finally, we implement asset trading prototype based on Hyperledger Fabric and evaluate the performance of model. The experimental results show that the proposed multi-channel blockchain-based framework realized intra-channel date sharing and extra-channel privacy protection. Our framework achieves enhanced security, high efficiency and strong traceability for assert trading.

基于区块链的隐私保护框架与多渠道资产交易访问控制模型

随着电子商务和智能设备的发展，产生了大量的资产交易数据和交易者身份信息。当数据存储在中心化的交易系统中时，对数据的安全性和隐私性提出了巨大的挑战。在此，考虑到资产交易中数据共享和数据隐私的需求，我们提出了一个基于区块链的隐私保护框架，以满足这两方面的要求。所提出的框架结合了多通道访问控制模型和智能合约，以提高许可通道内资产交易的安全性和透明度，同时维护这些通道外交易的隐私。此外，在市场效率和交易公平性方面，我们设计了双重拍卖的交易算法，使交易更加自动化和智能化。最后，我们基于 Hyperledger Fabric 实现了资产交易原型，并对模型的性能进行了评估。实验结果表明，所提出的基于多通道区块链的框架实现了通道内的日期共享和通道外的隐私保护。我们的框架为资产交易实现了更高的安全性、高效性和可追溯性。

期刊介绍： The aim of the Peer-to-Peer Networking and Applications journal is to disseminate state-of-the-art research and development results in this rapidly growing research area, to facilitate the deployment of P2P networking and applications, and to bring together the academic and industry communities, with the goal of fostering interaction to promote further research interests and activities, thus enabling new P2P applications and services. The journal not only addresses research topics related to networking and communications theory, but also considers the standardization, economic, and engineering aspects of P2P technologies, and their impacts on software engineering, computer engineering, networked communication, and security. The journal serves as a forum for tackling the technical problems arising from both file sharing and media streaming applications. It also includes state-of-the-art technologies in the P2P security domain. Peer-to-Peer Networking and Applications publishes regular papers, tutorials and review papers, case studies, and correspondence from the research, development, and standardization communities. Papers addressing system, application, and service issues are encouraged.
