certificate renewal
(I) The act or process by which the validity of the data binding
asserted by an existing public-key certificate is extended in time
by issuing a new certificate. (See: certificate rekey, certificate
update.)
(C) For an X.509 public-key certificate, this term means that the
validity period is extended (and, of course, a new serial number
is assigned) but the binding of the public key to the subject and
to other data items stays the same. The other data items are
changed, and the old certificate is revoked, only as required by
the PKI and CPS to support the renewal. If changes go beyond that,
the process is a "certificate rekey" or "certificate update".
