Certificates
Certificates can be used for making secure connections through a browser or for
authenticating a downloaded application.
There are three kinds of certificates:
• authority certificates - these can be used for authenticating downloaded
applications, authenticating other authority certificates and for authenticating
servers. They may be pre-installed, or can be downloaded while browsing.
• user certificates - these are used for client authentication and/or making a digital
signature. This means that user certificates can be used to prove the identity of a
given user over a wireless connection. User certificates can also be used for
encrypting and digitally signing information, thus ensuring the confidentiality and
integrity of mobile transactions. They may be pre-installed in the security module
(see Security module), or can be downloaded while browsing.
• server certificates - these may be sent by the server to the phone in case of server
authenticated (in contrast to anonymous) secure connection establishment.
When received, the validity of the certificates is checked using the local time and
authority certificates stored locally.
To view the lists of authority certificates and user certificates stored in your Vertu
phone:
1. From the Home screen, select Menu > Settings > Security > Authority
certificates/User certificates.
2. Select View.
To select the purpose of authority certificates stored in your Vertu phone:
IMPORTANT: Before changing any certificate settings, you must make
sure that you trust the owner of the certificate and that the certificate
belongs to the listed owner.
