Abstract
A method of transferring digital certificates from a digital-certificate transferring apparatus to a communications counterpart. The method includes authenticating the communications counterpart using a common certificate and transferring a normal certificate to the communications counterpart when the authenticating succeeds. The method further includes receiving a first normal certificate at an address from said communications counterpart, and when, it is determined to be necessary, transferring to the communications counterpart a second normal certificate along with the information identifying the communications counterpart and an address corresponding to a second normal certificate. The second normal certificate is of a different type than the first normal certificate.
