Storing Validation Parameters in PKCS#8

在PKCS#8中存储验证参数

Abstract

摘要

This memo describes a method of storing parameters needed for private-key validation in the Private-Key Information Syntax Specification as defined in PKCS#8 format (RFC 5208). It is equally applicable to the alternative implementation of the Private-Key Information Syntax Specification as defined in RFC 5958.

本备忘录描述了在PKCS#8格式(RFC 5208)中定义的私钥信息语法规范中存储私钥验证所需参数的方法。它同样适用于RFC 5958中定义的私钥信息语法规范的替代实现。

The approach described in this document encodes the parameters under a private enterprise extension and does not form part of a formal standard.

本文档中描述的方法对私有企业扩展下的参数进行编码,不构成正式标准的一部分。

1. Introduction
1. 介绍

RSA or DSA private keys generated using the Shawe-Taylor prime generation algorithm described in [FIPS186-4] allow for parameter validation, i.e., they verify whether the primes are actually prime and were correctly generated. That is done by generating the parameters from a known seed and a selected hash algorithm.

使用[FIPS186-4]中所述的Shawe-Taylor素数生成算法生成的RSA或DSA私钥允许进行参数验证,即验证素数是否实际为素数且是否正确生成。这是通过从已知种子和选定的哈希算法生成参数来实现的。

Storing these parameters in a private-key format such as the RSA Private-Key Syntax from PKCS#1 [RFC8017] or common representations for DSA private keys does not allow information needed for validation to be attached to the parameters. The purpose of this document is to describe such a method using the Private-Key Information Syntax Specification as defined in [RFC5208] and the alternative specification described in [RFC5958].

以私钥格式存储这些参数,例如PKCS#1[RFC8017]中的RSA私钥语法或DSA私钥的通用表示形式,不允许将验证所需的信息附加到参数。本文件的目的是使用[RFC5208]中定义的私钥信息语法规范和[RFC5958]中描述的替代规范来描述此类方法。

The approach described in this document encodes the parameters under a private enterprise extension and does not form part of a formal standard. The encoding can be used as is or as the basis for a standard at a later time.

本文档中描述的方法对私有企业扩展下的参数进行编码,不构成正式标准的一部分。编码可以按原样使用,也可以在以后用作标准的基础。

2. ValidationParams Attribute
2. ValidationParams属性

The information related to the validation parameters is stored as an attribute in the PrivateKeyInfo structure. The attribute is identified by the id-attr-validation-parameters object identifier and contains as AttributeValue a single ValidationParams structure.

与验证参数相关的信息作为属性存储在PrivateKeyInfo结构中。该属性由id attr validation parameters对象标识符标识,并包含一个ValidationParams结构作为AttributeValue。

     id-attr-validation-parameters OBJECT IDENTIFIER ::=
                                              {1 3 6 1 4 1 2312 18 8 1}
        
     id-attr-validation-parameters OBJECT IDENTIFIER ::=
                                              {1 3 6 1 4 1 2312 18 8 1}
        
     ValidationParams ::= SEQUENCE {
         hashAlgo OBJECT IDENTIFIER,
         seed OCTET STRING
     }
        
     ValidationParams ::= SEQUENCE {
         hashAlgo OBJECT IDENTIFIER,
         seed OCTET STRING
     }
        

The algorithm identifier in ValidationParams should be a hash algorithm identifier for the methods described in [FIPS186-4]. The ValidationParams sequence must be DER encoded [ITU-T-X690].

ValidationParams中的算法标识符应为[FIPS186-4]中所述方法的哈希算法标识符。ValidationParams序列必须进行DER编码[ITU-T-X690]。

3. Example Structure
3. 示例结构

The following structure contains an RSA key generated using the algorithm from Section B.3.3 of [FIPS186-4], with SHA2-384 hash. The seed used is 8af4328c87bebcec31e303b8f5537effcb6a91d947084d99a369823b36f01462 (hex encoded).

以下结构包含使用[FIPS186-4]第B.3.3节中的算法生成的RSA密钥以及SHA2-384哈希。使用的种子是8af4328c87bebcec31e303b8f5537effcb6a91d947084d99a369823b36f01462(十六进制编码)。
