14. Encryption
14.1. Introduction
To secure all communication between the WCAOP
and the wireless delegate units, all information that
is passed over the radio link is encrypted by default,
using a default encryption key. This key is identical
for all Televic equipment.
To this default key, a custom encryption key can be
added. This further enhances the confidentiality, but
can also be used to control access in an environment
where multiple adjacent rooms are using a Confidea
conference system. In this way, access can be
restricted to a single room or a selection of rooms.
The custom key as it were adds a unique relationship
between a wireless unit and a given access point.
14.2. Default encryption
By default the system uses an encryption mechanism
that is known by each unit in the wireless conference
configuration.
By using this setting it is possible to add new units in
the conference configuration or using the delegate
units with other
WCAP ’s at any time (also see
Initialization)
14.3. Setting the default
encryption
The default encryption mechanism can be set by
following these steps:
19. Select the “Key assignment” sub tab in the
“Encryption” menu from the web server.

the default encryption mechanism

Note:
The advanced encryption mechanism
used in the Confidea system makes
decryption by third party equipment
practically impossible.
