Certificates
There are three kinds of certificates:
1 Server certificates: A server certificate is sent from the server to the
phone and its validity is checked using the authority certificates
stored in the phone or the security module. This way you can be
certain that a WAP gateway or a WAP server is the one it claims to be.
You will see a note on the phone display if the identity of the WAP
server or WAP gateway cannot be verified, if the WAP server or WAP
gateway certificate is not authentic or if you do not have the right
authority certificate in your phone.
2 Authority certificates: Authority certificates are used by some WAP
services, such as banking services, for checking signatures or server
certificates or other authority certificates.
You can download the certificate from a WAP page, if the WAP service
supports the use of authority certificates. After the download, you
can view the certificate and then save or delete it. If you save the
certificate, it is added to the certificate list in the phone. Authority
certificates may also be available in the security module.
3 User certificates: User certificates are issued to users by a Certifying
Authority. They associate a user with a specific private key in a
security module, and they are stored in the module by the SIM card
issuer or the service provider.
