Certificates
There are three kinds of certificates; server certificates, authority certificates, and
user certificates. Authority certificates can either be saved in the security module
by the SIM card issuer or service provider, or they can be downloaded from a WAP
page and saved in the phone’s memory. User certificates are saved in the security
module by the SIM card issuer or the service provider. Server certificates are not
saved.
• Server certificates
A server certificate is sent from the WAP server to the phone and its validity is
checked using the authority certificates saved on the phone or in the security
module. The phone tells you when the identity of the WAP server or WAP
gateway cannot be verified, when the WAP server or WAP gateway certificate
is not authentic and when you do not have the correct authority certificate on
your phone.
The security indicator is displayed during a WAP connection if the data
transmission between the phone and the WAP gateway or WAP server
(identified by the IP address in the Edit active service settings is encrypted.
