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