摘要

数据交易正变得越来越重要，因为它具有巨大的价值。基于区块链的数据市场可以为数据交换提供安全透明的平台。为了促进这一点，近几十年来，为数字产品开发公平的数据交换协议已经引起了相当大的关注。零知识或有支付（ZKCP）协议借助区块链和零知识证明实现了无需信任的公平交换。然而，在实际的数据市场中应用该协议并非易事。在本文中，在实际的公共数据市场中应用ZKCP协议时，确定了几种潜在的攻击。为了解决这些问题，我们提出了SmartZKCP，这是一种增强的解决方案，提供了改进的安全措施和更高的性能。该协议是形式化的，以确保公平和安全，防止潜在的攻击。此外，SmartZKCP提供效率优化和最小化通信成本。评估结果表明，SmartZKCP既实用又高效，适用于数据交换市场。

SmartZKCP: Towards practical data exchange marketplace against active attacks

The trading of data is becoming increasingly important as it holds substantial value. A blockchain-based data marketplace can provide a secure and transparent platform for data exchange. To facilitate this, developing a fair data exchange protocol for digital goods has garnered considerable attention in recent decades. The Zero Knowledge Contingent Payment (ZKCP) protocol enables trustless fair exchanges with the aid of blockchain and zero-knowledge proofs. However, applying this protocol in a practical data marketplace is not trivial.

In this paper, several potential attacks are identified when applying the ZKCP protocol in a practical public data marketplace. To address these issues, we propose SmartZKCP, an enhanced solution that offers improved security measures and increased performance. The protocol is formalized to ensure fairness and secure against potential attacks. Moreover, SmartZKCP offers efficiency optimizations and minimized communication costs. Evaluation results show that SmartZKCP is both practical and efficient, making it applicable in a data exchange marketplace.
