Configuring the conference system
68
Using default encryption
̈
In the “ default key ” box, select the “ Use default key ” option button.
The setting is saved. The system encrypts all radio signals with the
default encryption key. All components of the WiCOS series can
communicate with each other using this encryption key.
Using custom encryption To use custom encryption and protect the system against unauthorized
access by further WiCOS conference units:
̈
Initialize all required conference units with the access point (see
page 63).
̈
If necessary, use the “ Unit monitoring ” function to check that only
“wanted” conference units are initialized (see page 62).
̈
In the “ custom key ” box, select one of the “ Use custom key ... ” option
buttons.
̈ Generate an encryption key by clicking “ Calc. ” (“ Calculate ”).
An arbitrary key is generated in the corresponding “ Use custom key ... ”
field. The key is saved in this field.
Or:
̈
Enter a custom key into one of the “ Use custom key ... ” fields.
The key must consist of 32 hexadecimal characters. You can use
– numbers from 0 to 9 and
– letters from A to F.
If you enter a key shorter than 32 characters, the missing characters
will be filled in with zeros. If you enter a key longer than 32 characters,
the exceeding characters will be dropped. The entered key is saved in
the corresponding “
Use custom key ... ” field.
To assign the custom encryption key to the currently initialized conference
units:
̈
Click “ Upl. key ” (“ Upload key ”).
A safety query appears.
̈ Click “ OK ” to assign the custom encryption key to the initialized
conference units.
The custom encryption key is transferred to all currently initialized
conference units. During the transfer, the microphone LED
0 and the
signal light ring 2 of the conference units flash red. You can use the
current conference configuration again the next time you switch the
conference system on.
To add a conference unit to a conference configuration that uses custom
encryption:
̈
Initialize all required conference units with the access point (see
page 63).
If you select the default encryption “ default key ”, you can use all
WiCOS conference units without restrictions.
Only switched-on conference units that have been assigned the
custom encryption key can be used in the encryption-protected
conference configuration.
