标准摘要
[中文适用范围]： 本部分规定了盲数字签名机制以及三种变体的盲数字签名机制：部分披露、选择性披露和可追溯的盲数字签名机制。所有机制的安全性均基于离散对数问题。对于每种机制，本部分还指定了以下内容：——实体密钥生成过程；——盲签名生成过程；——签名验证过程。此外，本部分还为具有选择性披露的盲签名机制指定了呈现过程，并为可追溯的盲签名机制指定了请求者追踪过程和签名追踪过程。 [外文原描述]： ISO/IEC 18370-2:2016 specifies blind digital signature mechanisms, together with mechanisms for three variants of blind digital signatures. The variants are blind digital signature mechanisms with partial disclosure, blind digital signature mechanisms with selective disclosure and traceable blind digital signature mechanisms. The security of all the mechanisms in ISO/IEC 18370-2:2016 is based on the discrete logarithm problem. For each mechanism, ISO/IEC 18370-2:2016 specifies the following: - the process for generating the keys of the entities involved in these mechanisms; - the process for producing blind signatures; - the process for verifying signatures. ISO/IEC 18370-2:2016 specifies another process specific to blind signature mechanisms with selective disclosure, namely, the following: - the presentation process. Furthermore, ISO/IEC 18370-2:2016 specifies other processes specific to traceable blind signature mechanisms, namely, the following: a) the process for tracing requestors; b) the process for tracing signatures; c) the requestor tracing evidence evaluation process (optional); d) the signature tracing evidence evaluation process (optional).
