A difference among the reasons listed, however, is that a computer theft or loss can means the user s private key is compromised and, therefore, the certificate associated with the private key should be revoked. There is no reason to revoke the certificate for the other reasons in this list because the user s private key is not compromised.

When you enable key archival at a Windows Server 2003 enterprise CA, the key recovery process has two management roles:

Certificate manager. The certificate manager Common Criteria role is responsible for extracting the encrypted private key from the CA database in a binary large object (BLOB) file format. The certificate manager also determines which key recovery agent can decrypt each encrypted private key. Key recovery agent. The key recovery agent is responsible for decrypting the private key from the BLOB file extracted by the certificate manager. Once the key recovery agent extracts the private key, the PKCS #12 file must be distributed to the original user.

Although it is recommended that you assign separate people to the certificate manager and key recovery agent roles, a single person can hold both. Because the key recovery agent role is not a required or defined Common Criteria role, there are no operating system restrictions on one user holding both roles. Your organization s security policy for data recovery must determine whether these two roles must be held by separate employees.

When a certificate template specifies key archival, the private key associated with a certificate request must be securely transmitted from the requesting client computer to the CA for archival in the CA database. When the client requests a certificate that has key archival enabled, the process shown in Figure 14-1 takes place:

The key archival process
1. The client queries the CN=Enrollment Services,CN=Public Key Services, CN=Services,CN=Configuration,DC=ForestRootDomain container to find an enterprise CA. 2. The client makes an authenticated Distributed Component Object Model (DCOM) connection to the selected enterprise CA and requests its CA Exchange certificate. 3. The CA sends the CA Exchange certificate to the client computer. 4. The client performs the following tests on the CA Exchange certificate:
Verifies that the CA Exchange certificate is signed by the CA s signing certificate. This ensures that the private key is being sent to the correct CA and only the intended CA can decrypt the private key. Performs a certificate validation and revocation status check on the CA Exchange certificate.
5. The client encrypts the private key corresponding to the request with the CA Exchange certificate s public key, builds a Certificate Management Message over Cryptographic Message Syntax (CMC) request, and sends a CMC full PKI request to the CA.

6. The CA validates that the encrypted private key is the matched key to the public key in the CMC request. 7. The CA validates the signature on the request with the public key in the request to ensure that the contents of the request are not modified. 8. The CA encrypts the user request s private key with a random 3DES symmetric key and then encrypts the symmetric key with one or more Key Recovery Agent certificate public keys defined in the CA s properties. 9. The CA saves the encrypted key BLOB which contains the encrypted private key and the symmetric key encrypted with one or more Key Recovery Agent certificate s public keys to the CA database.
10. The CA processes the certificate request normally and responds to the client with a CMC full PKI response containing the certificate issued to the requestor. The result of this process is that the client receives a certificate signed by the issuing CA, and the certificate and the associated private key are archived in the CA database. Because of the encryption, only a designated key recovery agent can decrypt the private key material stored in the CA database.
