Nokia 6820i warranty Security Module, Digital Signature

Services

Before changing these settings, make sure that you really trust the owner of the certificate and that the certificate really belongs to the listed owner.

SECURITY MODULE

The security module can contain certificates as well as private and public keys. The security module may improve the security services for applications requiring browser connection, and allows you to use a digital signature. The certificates are saved in the security module by the service provider.

Select Menu > Services > Settings > Security settings > Security module settings. Select from the following module settings:

Security module details—to show the security module title, status, manufacturer and serial number.

Module PIN request—to set the phone to ask for the module PIN when using services that are provided by the security module. Key in the code, and select On. To disable the module PIN request, select Off.

Change module PIN—to change the module PIN, if allowed by the security module. Key in the current module PIN code; then key in the new code twice.

Change signing PIN—to change a signing PIN. Select the signing PIN that you want to change. Key in the current PIN code; then key in the new code twice.

DIGITAL SIGNATURE

You can create digital signatures with your phone. The signature can be traced back to you through the private key in the security module and the user certificate that was used to create the signature. Using the digital signature may be considered to be equal to a normal signature on any legal 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 that needs to be signed (possibly including amount, date, etc.) will be shown.

Check that the header text is Read and that the digital signature icon is 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 add the digital signature to the text, read all of the text before you select Sign. The text may not fit on 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. Key in the signing PIN, and select OK. The digital signature icon will disappear, and the service may display a confirmation of your purchase.
