【Abstract】Monero is one of the privacy-preserving cryptocurrencies employing CryptoNote protocol. The privacy features in Monero are provided by cryptographic techniques such as linkable ring signature and one-time public key. Recent studies show that the majority of Monero inputs are traceable prior to mandatory RingCT transaction. After the RingCT was implemented, the problems were mitigated. We propose a novel attack to reduce the anonymity of Monero transactions or even to fully deanonymise the inputs. The proposed protocol can be launched in RingCT protocol and enables multiple attackers to collaborate without trusting each other. The attack scheme can be planted in the existing Monero services without extra fees and without putting the users' money at risk.

【标题】Monero环攻击：重建0mixin交易效应
【摘要】Monero是采用CryptoNote协议的隐私保护加密货币之一。Monero中的隐私功能由加密技术提供，如可链接环签名和一次性公钥。最近的研究表明，大多数Monero输入在强制RingCT交易之前是可追踪的。实施RingCT后，问题得到缓解。我们提出了一种新的攻击，以减少Monero事务的匿名性，甚至完全消除输入的非对称性。该协议可以在RingCT协议中启动，使多个攻击者能够在不相互信任的情况下进行协作。攻击方案可以植入现有的Monero服务中，无需额外费用，也不会让用户的资金面临风险。
