There are three kinds of certificates: server certificates, authority 
certificates, and user certificates. You may receive these certificates 
from your service provider. Authority certificates and user certificates 
may also be saved in the security module by the service provider.
To view the list of the authority or user certificates downloaded into 
your phone, select 
Menu
> 
Settings
> 
Security
> 
Authority certificates
 
or 
User certificates

 is displayed during a connection, if the data transmission between 
the phone and the content server is encrypted.
The security icon does not indicate that the data transmission between the 
gateway and the content server (or place where the requested resource is stored) 
is secure. The service provider secures the data transmission between the 
gateway and the content server.
Digital signature
You can make digital signatures with your phone if your SIM card has a 
security module. Using the digital signature can be the same as signing 
your name to a paper bill, contract, or other document.
To make a digital signature, select a link on a page, for example, the title 
of the book you want to buy and its price. The text to sign, which may 
include the amount and date, is shown.
Check that the header text is 
Read
 and that the digital signature icon 
 is shown.
If the digital signature icon does not appear, there is a security breach, 
and you should not enter any personal data such as your signing PIN.
To sign the text, read all of the text first, and select 
Sign
.
The text may not fit within a single screen. Therefore, make sure to scroll 
through and read all of the text before signing.
Select the user certificate you want to use. Enter the signing PIN (see 
Access codes p. 9), and select 
OK
. The digital signature icon disappears, 
and the service may display a confirmation of your purchase.
