标准范围

本文档指定了匿名数字签名机制，其中验证者使用多个公钥来验证数字签名。本文件规定:-使用多个公钥的匿名数字签名机制的一般描述；-提供这种匿名数字签名的各种机制。对于每种机制，本文档规定了以下过程:-生成每个用户的私钥和公钥；-制作签名；-验证签名；-链接签名(如果机制支持链接)；-跟踪签名（如果机制支持跟踪）；-产生具有阈值能力的签名(如果所述机制支持阈值能力)；-验证具有阈值能力的签名(如果机制支持阈值能力)。本文档没有定义公钥基础设施(PKI)的实现以及不同实体交换、提取和验证其各自的公钥证书的方法。

This document specifies anonymous digital signature mechanisms in which a verifier uses multiple public keys to verify a digital signature.

This document provides:

— a general description of an anonymous digital signature mechanism using multiple public keys;

— a variety of mechanisms that provide such anonymous digital signatures.

For each mechanism, this document specifies the process for:

— generating the private key and public key of each user;

— producing signatures;

— verifying signatures;

— linking signatures (if the mechanism supports linking);

— tracing signatures (if the mechanism supports tracing);

— producing signatures with threshold capability (if the mechanism supports a threshold capability);

— verifying signatures with threshold capability (if the mechanism supports a threshold capability).

This document does not define the implementation of a public key infrastructure (PKI) and the means for distinct entities to exchange, extract and verify their respective public key certificates.
