本公告描述了对门罗币可链接环签名方案的修改,该方案允许双密钥输出作为环成员。密钥图像与双重输出中的一次性公钥相关联,从而防止该交易中的两个密钥被单独使用。该方法适用于非交互式退款交易。我们讨论该方案的安全影响。
This bulletin describes a modification to Monero’s linkable ring signature scheme that permits dualkey outputs as ring members. Key images are tied to both output one-time public keys in a dual, preventing both keys in that transaction from being spent separately. This method has applications to non-interactive refund transactions. We discuss the security implications of the scheme.
