msgid "In cryptography, a ring signature is a type of digital signature that can be performed by any member of a group of users that each have keys. Therefore, a message signed with a ring signature is endorsed by someone in a particular group of people. One of the security properties of a ring signature is that it should be computationally infeasible to determine *which* of the group members' keys was used to produce the signature."
msgstr "在密码学中，环形签名是一种数字签名，可以由一组用户中的任何成员执行，每个用户都有密钥。因此，一个带有环签名的消息是由特定人群中的某个人背书的。环签名的安全特性之一是，不能通过计算确定*哪个*组成员的密钥才是签名。"

msgid "For instance, a ring signature could be used to provide an anonymous signature from \"a high-ranking White House official\", without revealing which official signed the message. Ring signatures are right for this application because the anonymity of a ring signature cannot be revoked, and because the group for a ring signature can be improvised (requires no prior setup)."
msgstr "例如，环签名可以用来提供一种来自“白宫高级官员”的匿名签名，而不透露是哪位官员签署了这条信息。环签名适合这个应用，因为环签名的匿名性不能被撤销，而且一个环签名的是可以临时组成的（不需要预先设置）。"

msgid "A ring signature makes use of your @account keys and a number of public keys (also known as outputs) pulled from the @blockchain using a triangular distribution method. Over the course of time, past outputs could be used multiple times to form possible signer participants. In a \"ring\" of possible signers, all ring members are equal and valid. There is no way an outside observer can tell which of the possible signers in a signature group belongs to your @account. So, ring signatures ensure that transaction outputs are untraceable. Moreover, there are no @fungibility issues with Monero given that every transaction output has plausible deniability (e.g. the network can not tell which outputs are spent or unspent)."
msgstr "一个环签名，由你的@账户密钥以及通过三角形分布方法从@区块链中提取的多个公钥（也称为输出）组成。随着时间的推移，可以多次使用过去的输出来形成可能的签名参与者。在可能的签名者的“环”中，所有的环成员都是平等和有效的。外部观察者无法知道签名组中哪些签名者属于您的@账户。因此，环签名确保交易输出不可跟踪。此外，门罗币不存在@可替换性的问题，因为每个交易输出都有合理的可否认性（例如，网络无法分辨哪些输出已使用或未使用）。"
