Sim Services - Nokia 6030 User Manual

Digital signature
You can make digital signatures with your phone if your SIM card has a security
module. The signature can be traced back to you by the private key on the security
module and the user certificate that was used to perform the signature. 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.) is shown.
Check that the header text is Read and that the digital signature icon
Note: 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.
The text may not fit within a single screen. Make sure to scroll through and read
all of the text; then select Sign.
Select the user certificate you want to use. Enter the signing PIN (see "General
information," p. 8), and select OK. The digital signature icon disappears, and the
service may display a confirmation of your purchase.
