White paper G900c
22 August 2008
Browser
G900c features an integrated Opera™ 8 browser.
This browser has been designed to display
practically all Web pages on the Internet. The
browser supports the de facto HTML standard
‘street HTML’ (used by most Web developers),
JavaScript™ technology, frames, and the ability to
add plug-in applications. Users thus can access
their favourite Web pages also from the phone.
It is easy to switch between portrait and landscape
presentation, as well as change from normal view
with scroll bars to full screen view. Pen motions are
used to slide the page on the screen.
Users can select ‘fit to screen’ to reformat pages to
fit inside the screen width and eliminate the need
for horizontal scrolling (Small Screen Rendering is
supported).
Some key features:
• Flash Lite 3 support (from maintenance release
1 of the phone software).
• By tapping and holding on a bookmark the page
is displayed in a new window.
• By tapping and holding on a link a context-sen-
sitive menu of alternative actions is displayed:
an http link would give the options Open, Open
in new window, Open in background and Send
as.
• Includes Secure downloads manager – espe-
cially useful for downloading commercial media
objects that need to be paid for.
• Pages can be saved for offline viewing.
• All private data can be cleared with one com-
mand.
• Built-in pop-up blocking.
Browser security
G900c supports 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.
TLS Security
When using certain Internet services such as
banking, the user may require a secure connection
between the phone and the Web site. G900c is
based on the WAP 2.0 specification where security
functionality is specified with a technology called
WAP TLS Profile (Wireless Application Protocol
Transport Layer Security).
The Internet protocols that handle the connection,
its transport and its security are structured in
protocol layers. The security is handled by the TLS
layer operating above the transport protocol layer.
There are three TLS classes that define the levels
of security for a TLS connection:
• Anonymous TLS involves encryption with no
authentication.
• Server authentication involves encryption with
server authentication.
• Client authentication involves encryption with
both server and client authentication
Server
authentication
Requires a server certificate
stored at the server side and a
trusted certificate stored at the
client side.
Client
authentication
Requires a client certificate
stored at the client side and a
trusted certificate stored at the
server side.
