Browser security
P990i supports the TLS/SSL to provide a secure
encrypted link between the browser and the web
site. This method is commonly used for secure
transactions on the web. An icon in the display
indicates when a secure connection is in use.
Certificates
To use secure connections, the user needs to have
certificates saved in the phone. User certificates
can be downloaded. There are two types of certifi-
cates:
P990i is loaded with WTLS/X509 certificates from
Baltimore, Entrust, GlobalSign, GTE Cybertrust,
RSA, Thawte and VeriSign.
RSS feeds
RSS provides a way for web sites to distribute their
content outside of a web browser. A news web site
might have an RSS feed which contains breaking
stories, while a magazine web site may provide an
RSS feed with excerpts of their latest articles.
An RSS feed is a file containing a list of news items,
each of which has a title, a description and a URL
link to read more on the content provider's web
site.
With the RSS Feeds application the user gets infor-
mation from the Internet into an easy-to-view for-
mat without browsing the web sites. The user can
browse information from dozens - or hundreds - of
web sites without ever visiting them.
RSS Feeds includes the following features:
• Subscription.
• Update feeds manually or via a predefined
schedule.
• Organize feeds into folders.
• Read news items.
• Send a news item to another device via email,
SMS, MMS, Bluetooth™ connectivity or infra-
red.
• Link to more information via the web browser.
Certificate
authority A certificate used to verify that a
Web site is genuine. If the phone
has a stored certificate of a cer-
tain type, it means the user can
trust all WAP gateways which
present a certificate that can be
verified by the trusted certificate.
Certificates can be preinstalled
in the phone or downloaded
from the trusted supplier's Web
page.
User
certificate
A personal certificate that veri-
fies the user's identity. A bank
that the user has a contract with
may issue this kind of certificate.
