Authority certificates
For using some services, such as banking services, you need security certificates. Using the certificates
can help you improve the security of connections between your phone and a gateway or server, if the
Connection security is set to On .
You can download authority certificate from a page, if the service supports the use of authority
certificates. After the download, you can view the certificate and then save or delete it. Saved
certificates are added to the certificate list in the phone.
The phone indicates if the identity of the server or gateway cannot be verified, if the server or gateway
certificate is not authentic or if you do not have the correct authority certificate in your phone.
Viewing the list of authority certificates
Press Menu , select Services , Settings , Security settings and Authority certificates .
See also Security info in Using the phone keys while browsing on page 101.
Security indicator
If the security indicator is displayed during a connection, the data transmission between the phone
and the gateway or server (identified by the IP address in the Edit active service settings ) is
encrypted.However, the security indicator does not indicate that the data transmission between the
gateway and the content server (the location where the requested resource is stored) is secure. It is up
to the service provider to secure the data transmission between the gateway and the content server.
