Abstract (en)
[origin: WO03049358A1] A method is provided for authenticating a digital certificate issued by a certificate authority (200) for being used in conjunction with a user's public key and initially includes the step of signing a message digest derived form said public key with an anti-forgery private key thereby forming an anti-forgery signature. Next, the anti-forgery signature is inserted into a request for the digital certificate. Finally, the request for the digital certificate is forwarded to the certificate authority (200).
