Cache memory
A cache is a memory location that is used to store data temporarily. If you have
tried to access or have accessed confidential information requiring passwords,
empty the cache after each use. The information or services you have accessed are
stored in the cache.
To clear the cache from the menu, select Services > Clear the cache.
To clear the cache while browsing, select Options > Other options > Clear the cache.
Certificates
To use some WAP services, such as banking services, you need an authority certificate.
Using the certificate can help you to improve the security of connections between
your phone and a WAP server.
You can download the certificate from a WAP page if the WAP service supports the use
of authority certificates. After the download, you can view the certificate, then save or
delete it. If you save the certificate, it is added to the list of certificates in the phone.
Your phone alerts you if the identity of the WAP server or WAP gateway cannot be
verified or is not authentic.
To view the list of authority certificates, from the menus, select Services > Settings >
Security settings > Authority certificates > Certificate list.
Security module
The security module improves security services and allows you to use a digital
signature. It can contain certificates and public and private keys. Your service
provider saves the certificates in the security module.
From the menus, select Services > Settings > Security settings > Security
module settings and one of the following:
Security module details—View the security module title, status, manufacturer, and
serial number.
Module PIN request—Select On to set the phone to ask for the module PIN when
using services provided by the security module.
Change module PIN—Change the module PIN, if allowed by the security module.
