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 create digital signatures with your phone if your SIM card has a security
module. The digital signature is the same as signing your name to a paper bill,
contract, or other document.
To create 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 be signed is shown and
may include the amount and date.
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;
do 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, and enter the signing PIN. The digital
signature icon disappears, and the service may display a confirmation of your
purchase.
