Sim Services - Nokia 7380 User Manual

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.
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 using 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 (for example, amount
and date) is shown.
Check that the header text is Read
shown.
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.
To sign the text, read all of the text first, then 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 that you want to use. Enter the signing PIN (see
"Access codes," p. 7).
