Certificates
To use secure connections, the user needs to have
certificates saved in the phone. Certificates can be
downloaded and installed when required. There are
two types of certificates:
Certificate A trusted certificate used to
authority verify that a Web site is genuine.
If the phone has a stored
trusted certificate of a certain
type, it means the user can trust
all Web sites which present a
certificate that can be verified
by the trusted certificate.
Certificates are preinstalled in
the phone and can be
downloaded from the trusted
supplier's Web page.
User A personal certificate that
certificate verifies the user's identity. A
bank that the user has a
contract with may issue this
kind of certificate.
Preinstalled in G900c are X.509 certificates from
Baltimore, Entrust, Geotrust, GlobalSign, GTE
Cybertrust, RSA, Sony Ericsson, Thawte and
VeriSign.
