摘要： 为解决区块链数据交易中用户身份等隐私数据泄露问题，提出一种基于联盟链和群签名的数据资产交易方案。采用联盟链节点准入机制实现注册用户的身份认证，引入可链接群签名技术实现用户交易的匿名性和交易记录的可追溯性，通过智能合约正确执行链上数据公平交换策略。最后对所提出的方案进行理论分析和仿真实验，表明该方案可以实现更加安全高效的去中心化数据交易。

关键词: 联盟链, 数据交易, 群签名, 可追溯性, 智能合约

Abstract: To solve the data leakages of user identity and other privacy data in the process of data trading in blockchain, a data asset trading scheme based on alliance chain and group signature is proposed. This paper adopts alliance chain node access mechanism to realize the identity authentication of registered users. A linkable group signature technology is introduced to realize user anonymity and traceability in the process of trading. Meanwhile, a fair data exchange strategy is implemented on the chain by using the smart contract. Finally, theoretical analysis and simulation results show that the scheme can achieve decentralized data trading with higher security and efficiency.

Key words: alliance blockchain, data trading, group signature, traceability, smart contract
