Onionchain:平衡基于区块链的应用程序的隐私性和可追溯性

Onionchain: Towards Balancing Privacy and Traceability of Blockchain-Based Applications

Yue Zhang, Jian Weng, Jiasi Weng, Ming Li, Weiqi Luo

摘要:

随着区块链的普及,出现了严重的安全问题。同时实现隐私和可追溯性仍然是一个悬而未决的问题。已经为解决这些问题作出了努力,但这些问题可能取决于具体的情况。本文研究如何为这一开放问题提供一个更一般的解决方案。具体来说,我们提出了Onionchain,它具有一套协议,提供可追溯性和隐私性。正如术语所暗示的,我们的Onionchain受到了Onion路由的启发。我们仔细研究了洋葱路由的原理,并将其机制与区块链技术结合起来。我们提倡区块链社区在隐私和可追溯性方面采用Onionchain。为此,Onionchain的案例研究,它运行在车辆Ad Hoc网络(VANESTO)的背景下,提出,提供社区遵循的指导方针。系统的安全性分析和广泛的实验也进行了验证我们的安全和成本效益的洋葱链。

英文摘要:

With the popularity of Blockchain comes grave security-related concerns. Achieving privacy and traceability simultaneously remains an open question. Efforts have been made to address the issues, while they may subject to specific scenarios. This paper studies how to provide a more general solution for this open question. Concretely, we propose Onionchain, featuring a suite of protocols, offering both traceability and privacy. As the term implies, our Onionchain is inspired by Onion routing. We investigate the principles of Onion routing carefully and integrate its mechanism together with Blockchain technology. We advocate the Blockchain community to adopt Onionchain with the regards of privacy and traceability. To this end, a case-study of Onionchain, which runs in the context of Vehicular Ad Hoc Networks (VANETs), is proposed, providing the community a guideline to follow. Systematic security analysis and extensive experiments are also conducted to validate our secure and cost-effective Onionchain.
