Abstract

This document defines a Certificate Management protocol using CMS (CMC). This protocol addresses two immediate needs within the Internet PKI community:

1. The need for an interface to public key certification products and services based on [CMS] and [PKCS10], and 2. The need in [SMIMEV3] for a certificate enrollment protocol for DSA-signed certificates with Diffie-Hellman public keys.

A small number of additional services are defined to supplement the core certificate request service.

Throughout this specification the term CMS is used to refer to both [CMS] and [PKCS7]. For both signedData and envelopedData, CMS is a superset of the PKCS7. In general, the use of PKCS7 in this document is aligned to the Cryptographic Message Syntax [CMS] that provides a superset of the PKCS7 syntax. The term CMC refers to this specification.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119].

1. Protocol Requirements

- The protocol is to be based as much as possible on the existing CMS, PKCS#10 and CRMF specifications. - The protocol must support the current industry practice of a PKCS#10 request followed by a PKCS#7 response as a subset of the protocol. - The protocol needs to easily support the multi-key enrollment protocols required by S/MIME and other groups. - The protocol must supply a way of doing all operations in a single-round trip. When this is not possible the number of round trips is to be minimized. - The protocol will be designed such that all key generation can occur on the client. - The mandatory algorithms must superset the required algorithms for S/MIME. - The protocol will contain POP methods. Optional provisions for multiple-round trip POP will be made if necessary. - The protocol will support deferred and pending responses to certificate request for cases where external procedures are required to issue a certificate. - The protocol needs to support arbitrary chains of local registration authorities as intermediaries between certificate requesters and issuers.
