Abstract
A method and system for creating, reviewing and revoking, if necessary, a certificate for a client of a service provider of a communications network, wherein the client has a client private key and a client public key. The method includes the steps of establishing a communications link with the service provider through a dedicated communication channel; requesting a client certificate from the service provider; obtaining a caller-ID, including a telephone number from an operator of the dedicated communication channel; and creating the requested client certificate including the caller-ID. Preferably, the method also includes the step of verifying that the caller-ID obtained from the operator of the dedicated communication channel is the same as client identifying information provided by the client when requesting the client certificate. The certificate can be stored at a caller ID server or a client's storage. The method includes the steps of periodically reviewing issued certificates against a reverse telephone book to determine if the included telephone number is still associated with the client and revoking the certificate if it is not.
