5.6 Secure Web Connections
5.6.1 A Note on Supported Protocols
Nokia 9210 Communicator’s web browser supports the SSLv3 (Secure Sockets Layer version 3) protocol. Future
updates of the web browser plan to support TLSv1 (Transport Layer Security version 1) protocol. Unfortunately, some
server implementations of SSL are defective and fail the protocol negotiation if TLS is proposed by the client. To
guarantee interoperability with these servers, Nokia 9210 Communicator only uses SSL for web connections for the
time being. There is no difference in the level of security between SSL and TLS protocols, and SSLv3 is the most widely
supported security protocol for web at this time. TLS is still available to other applications that do not need to connect
to web servers.
When the connection is secure, the user sees a lock icon in the title bar and can see the ‘encrypted’ status in the
menu (Tools | Information | Status).
Figure 2: The lock icon is visible for pages retrieved over SSL (https://)
5.6.2 Certificates
In order to authenticate your server to the web browser, you need a certificate from a certification authority (CA).
Nokia does not endorse any specific CA. The authenticity of your server’s certificate is checked against a so-called root
certificate, which is installed in the Certificate Management application (in the Control Panel of Nokia 9210
Communicator). Root certificates from the most popular commercial CAs are factory-installed in Nokia 9210
Communicator. Users can install new root certificates themselves if required.
