• 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 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.
• Authority certificates
Authority certificates are used by some WAP services, such as banking services, for checking
signatures or server certificates or other authority certificates.
• 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.
