The saved, self-signed certificate can then be used for future SSL handshakes, eliminating the user intervention that was necessary to accept the certificate every time the router reloaded. Note To take advantage of autoenrollment and autoreenrollment, do not use either TFTP or manual cut-and-paste enrollment as your enrollment method.
Both TFTP and manual cut-and-paste enrollment methods are manual enrollment processes, requiring user input. Each suite consists of an encryption algorithm, a digital signature algorithm, a key agreement algorithm, and a hash or message digest algorithm. PKI support for validation of for X. An RA offloads authentication and authorization responsibilities from a CA.
When the RA receives a SCEP or manual enrollment request, the administrator can either reject or grant it on the basis of local policy. If the request is granted, it will be forwarded to the issuing CA, and the CA can be configured to automatically generate the certificate and return it to the RA. The client can later retrieve the granted certificate from the RA.
Automatic Certificate Enrollment Automatic certificate enrollment allows the CA client to automatically request a certificate from its CA sever. This automatic router request eliminates the need for operator intervention when the enrollment request is sent to the CA server.
Automatic enrollment is performed on startup for any trustpoint CA that is configured and that does not have a valid client certificate. When the certificate expires, a new certificate is automatically requested. Note When automatic enrollment is configured, clients automatically request client certificates. The CA server performs its own authorization checks; if these checks include a policy to automatically issue certificates, all clients will automatically receive certificates, which is not very secure.
Thus, automatic certificate enrollment should be combined with additional authentication and authorization mechanisms such as Secure Device Provisioning SDP , leveraging existing certificates, and one-time passwords.
Certificate and key rollover allows the certificate renewal rollover request to be made before the certificate expires by retaining the current key and certificate until the new, or rollover, certificate is available. After a specified amount of time, the rollover certificate and keys will become the active certificate and keys. The expired certificate and keys are immediately deleted upon rollover and removed from the certificate chain and CRL.
An optional renewal percentage parameter can be used with the auto-enroll command to allow a new certificate to be requested when a specified percentage of the lifetime of the certificate has passed. For example, if the renewal percentage is configured as 90 and the certificate has a lifetime of one year, a new certificate is requested In order for automatic rollover to occur, the renewal percentage must be less than The specified percent value must not be less than If a client certificate is issued for less than the configured validity period due to the impending expiration of the CA certificate, the rollover certificate will be issued for the balance of that period.
A minimum of 10 percent of the configured validity period, with an absolute minimum of 3 minutes, is required to allow rollover enough time to function. Tip If CA autoenrollment is not enabled, you may manually initiate rollover on an existing client with the crypto pki enroll command if the expiration time of the current client certificate is equal to or greater than the expiration time of the corresponding CA certificate.
The client will initiate the rollover process, which occurs only if the server is configured for automated rollover and has an available rollover server certificate. Note A key pair is also sent if configured by the auto-enroll re-generate command and keyword. It is recommended that a new key pair be issued for security reasons.
Certificate Enrollment Profiles Certificate enrollment profiles allow users to specify certificate authentication, enrollment, and reenrollment parameters when prompted. An RSA key pair a public and a private key is required before you can obtain a certificate for your router; that is, the end host must generate a pair of RSA keys and exchange the public key with the certificate authority CA to obtain a certificate and enroll in a PKI. After a certificate is validated as a properly signed certificate, it is authorized using methods such as certificate maps, PKI-AAA, or a certificate-based access control list ACL.
The revocation status is checked by the issuing certificate authority CA to ensure that the certificate has not been revoked. Certificate enrollment occurs between the end host requesting the certificate and the CA. Various methods are available for certificate enrollment. These credentials can be stored in the default location on the router, which is NVRAM, or other locations. The Cisco IOS software can maintain a different key pair for each identity certificate. Before this feature, Cisco IOS public key infrastructure PKI configurations allowed either one general-purpose key pair or a set of special-purpose key pairs an encryption and a signing key pair.
