9.2.3 Enabling H.235 Encryption
The H.235 encryption encrypts media streams using a negotiated encryption algorithm and key.
The encrypted media streams can be decrypted with the negotiated algorithm and key, thus
preventing unauthorized access.
Context
An IP network is not a quality-guaranteed or secure network. Encrypting the media streams
strengthens the security of video communications. To enable media stream encryption, both
parties in communication need to support the encryption functions.
Procedure
Step 1
Choose
Settings
>
Security
>
Encryption Policy
to select an H.235 encryption policy.
l
Disable
: No media stream is encrypted.
l
Enable
: Media streams are forced to be encrypted. If this option is selected, the terminal
can attend only an encrypted conference.
l
Maximum interconnectivity
: The media streams are encrypted only when a call can be
set up. If the other party does not support encryption, no media stream is forced to be
encrypted.
Step 2
Save the settings.
