Certificates
On your Smartphone you can add and delete public key certificates. These certificates
help establish your identity when you log on to a secure network, such as a corporate
network. Certificates also help establish the identity of other computers, such as servers,
with which you connect. This helps prevent unauthorized users from accessing your
Smartphone and its information.
You can store 2 types of certificates on your phone: personal certificates that establish
your identity, and root certificates that establish the identity of servers with which you
connect. Your Smartphone may include a set of preinstalled certificates.
