摘要 针对物联网终端交易的跨平台、去中心化、隐私、安全需求,提出基于联盟链的匿名交易方案,确保用户身份隐匿。通过划分基础域和互联域实现中心化身份认证和去中心化交易;对身份认证,提出基于Merkle树的双因素认证方案,实现各节点身份与消息的去耦;针对通信中明文消息暴露用户身份问题,提出基于CoinJoin思想的聚合签名隐私保护方案,混淆交易身份,以抵抗身份关联分析攻击;最后针对一致性和记账权问题,提出基于信誉评价策略的共识机制。安全性与效率分析表明,所提方案能以较低存储和计算开销保护终端身份隐私。

英文摘要 In order to meet the needs of cross-platform, decentralization, privacy and security of terminal transactions in the Internet of Things, this paper proposed an anonymous trading scheme based on alliance chain to ensure the concealment of user identity. It divided the basic domain and the Internet domain to realize centralized identity authentication and decentralized transaction. For identity authentication, the two-factor authentication scheme based on Merkle tree realized the decoupling of each node identity and message. In order to solve the problem that plaintext messages exposed user identity in communication, this paper proposed an aggregation signature privacy protection scheme based on CoinJoin, which was used to confuse transaction identity and resist identity association analysis attack. Finally, this paper proposed a consensus mechanism based on reputation evaluation strategy to solve the problems of message consistency and accounting rights. Security and efficiency analysis show that the proposed solution can protect identity privacy with lower storage and computational overhead.
