Certificates
The existence of a certificate does not offer any protection by itself;
the certificate manager must contain correct, authentic, or trusted
certificates for increased security to be available.
Before changing any certificate settings, you must make sure that
you really trust the owner of the certificate and that the certificate
really belongs to the listed owner.
There are two kinds of certificates:
>
server certificates
>
user certificates.
You may receive these certificates from your service provider. User
certificates may also be saved in the security module by the service
provider.
To view the list of the user certificates downloaded into your Vertu
phone:
From the stand-by display, press

Digital signature
You can make digital signatures with your Vertu 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:
1. 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.
2. Check that the header text is
R e a d
and that the digital signature
icon is shown.
3. If the digital signature icon does not appear, there is a security breach
and you should not enter any personal data, for example your signing
PIN.
4. To sign the text, read all of the text first, and press S i g n .
5. The text may not fit within a single screen. Therefore, make sure to
scroll through and read all of the text before signing.
6. Select the user certificate you want to use. Use the
N U M B E R
keys
to enter the signing PIN (see “PIN code” on page 13), and select
O K . The digital signature icon disappears, and the service may
display a confirmation of your purchase.
Important: Even if the use of certificates makes the risks
involved in remote connections and software installation
considerably smaller, they must be used correctly in order to
benefit from increased security.
