, the security indicator, is displayed during a connection if the data
transmission between the phone and the content server is encrypted.

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. 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 that you want to buy and its price. The text to sign (possibly including
amount, date, etc.) will be 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 then you can 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. Key in the signing PIN (see Access
codes on page 16) and press OK. The digital signature icon will disappear, and the
service may display a confirmation of your purchase.
