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 .

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.
