Appendix E. PKI Management Message Profiles (OPTIONAL).
This appendix contains detailed profiles for those PKIMessages that MAY be supported by implementations (in addition to the messages which MUST be supported; see Section 6 and Appendix D). Profiles for the PKIMessages used in the following PKI management operations are provided: o root CA key update o information request/response
o cross-certification request/response (1-way) o in-band initialization using external identity certificate Later versions of this document may extend the above to include profiles for the operations listed below (along with other operations, if desired). o revocation request o certificate publication o CRL publicationE.1. General Rules for Interpretation of These Profiles.
Identical to Appendix D.1.E.2. Algorithm Use Profile
Identical to Appendix D.2.E.3. Self-Signed Certificates
Profile of how a Certificate structure may be "self-signed". These structures are used for distribution of CA public keys. This can occur in one of three ways (see Section 4.4 above for a description of the use of these structures): Type Function ----------------------------------------------------------------- newWithNew a true "self-signed" certificate; the contained public key MUST be usable to verify the signature (though this provides only integrity and no authentication whatsoever) oldWithNew previous root CA public key signed with new private key newWithOld new root CA public key signed with previous private key Such certificates (including relevant extensions) must contain "sensible" values for all fields. For example, when present, subjectAltName MUST be identical to issuerAltName, and, when present, keyIdentifiers must contain appropriate values, et cetera.
E.4. Root CA Key Update
A root CA updates its key pair. It then produces a CA key update announcement message that can be made available (via some transport mechanism) to the relevant end entities. A confirmation message is NOT REQUIRED from the end entities. ckuann message: Field Value Comment -------------------------------------------------------------- sender CA name CA name body ckuann(CAKeyUpdAnnContent) oldWithNew present see Appendix E.3 above newWithOld present see Appendix E.3 above newWithNew present see Appendix E.3 above extraCerts optionally present can be used to "publish" certificates (e.g., certificates signed using the new private key)E.5. PKI Information Request/Response
The end entity sends a general message to the PKI requesting details that will be required for later PKI management operations. RA/CA responds with a general response. If an RA generates the response, then it will simply forward the equivalent message that it previously received from the CA, with the possible addition of certificates to the extraCerts fields of the PKIMessage. A confirmation message is NOT REQUIRED from the end entity. Message Flows: Step# End entity PKI 1 format genm 2 -> genm -> 3 handle genm 4 produce genp 5 <- genp <- 6 handle genp genM: Field Value recipient CA name -- the name of the CA as contained in issuerAltName
-- extensions or issuer fields within certificates

-- any authenticated protection alg.

body genp (GenRepContent)
CAProtEncCert present (object identifier one
of PROT_ENC_ALG), with relevant
value
-- to be used if end entity needs to encrypt information for
-- the CA (e.g., private key for recovery purposes)
SignKeyPairTypes present, with relevant value
-- the set of signature algorithm identifiers that this CA will
-- certify for subject public keys
EncKeyPairTypes present, with relevant value
-- the set of encryption/key agreement algorithm identifiers that
-- this CA will certify for subject public keys
PreferredSymmAlg present (object identifier one
of PROT_SYM_ALG) , with relevant
value
-- the symmetric algorithm that this CA expects to be used
-- in later PKI messages (for encryption)
CAKeyUpdateInfo optionally present, with
relevant value
-- the CA MAY provide information about a relevant root CA
-- key pair using this field (note that this does not imply
-- that the responding CA is the root CA in question)
CurrentCRL optionally present, with relevant value
-- the CA MAY provide a copy of a complete CRL (i.e.,
-- fullest possible one)
protection present
-- bits calculated using MSG_MAC_ALG or MSG_SIG_ALG
extraCerts optionally present
-- can be used to send some certificates to the end
-- entity. An RA MAY add its certificate here.
E.6. Cross Certification Request/Response (1-way)
Creation of a single cross-certificate (i.e., not two at once). The
requesting CA MAY choose who is responsible for publication of the
cross-certificate created by the responding CA through use of the
PKIPublicationInfo control.
Preconditions:
1. Responding CA can verify the origin of the request (possibly
requiring out-of-band means) before processing the request.
2. Requesting CA can authenticate the authenticity of the origin of
the response (possibly requiring out-of-band means) before
processing the response
The use of certificate confirmation and the corresponding server
confirmation is determined by the generalInfo field in the PKIHeader
(see Section 5.1.1). The following profile does not mandate support
for either confirmation.

E.7. In-Band Initialization Using External Identity Certificate
An (uninitialized) end entity wishes to initialize into the PKI with
a CA, CA-1. It uses, for authentication purposes, a pre-existing
identity certificate issued by another (external) CA, CA-X. A trust
relationship must already have been established between CA-1 and CA-X
so that CA-1 can validate the EE identity certificate signed by CA-X.
Furthermore, some mechanism must already have been established within
the Personal Security Environment (PSE) of the EE that would allow it
to authenticate and verify PKIMessages signed by CA-1 (as one
example, the PSE may contain a certificate issued for the public key
of CA-1, signed by another CA that the EE trusts on the basis of
out-of-band authentication techniques).
The EE sends an initialization request to start the transaction.
When CA-1 responds with a message containing the new certificate, the
end entity replies with a certificate confirmation. CA-1 replies
with a PKIConfirm to close the transaction. All messages are signed
(the EE messages are signed using the private key that corresponds to
the public key in its external identity certificate; the CA-1
messages are signed using the private key that corresponds to the
public key in a
certificate that can be chained to a trust anchor in the EE's PSE).
The profile for this exchange is identical to that given in Appendix
D.4, with the following exceptions:
o the EE and CA-1 do not share a symmetric MACing key (i.e., there
is no out-of-band shared secret information between these
entities);
o sender name in ir MUST be present (and identical to the subject
name present in the external identity certificate);
o protectionAlg of MSG_SIG_ALG MUST be used in all messages;
o external identity cert. MUST be carried in ir extraCerts field
o senderKID and recipKID are not used;
o body is ir or ip;
o protection bits are calculated according to the protectionAlg
field.
