Length of AES Key (ISDN only)
From this drop-down menu you can choose (for ISDN connections only) three AES key lengths:
From this drop-down menu you can choose (for ISDN connections only) three AES key lengths:
• 128 bits
• 192 bits
• 256 bits
• <Auto> (allows optimal choice according to the characteristics of the terminals negotiating the
videoconference session.)
Note: For an IP connection, the key length is always 128 bits.
Length of Prime DH Number Key (ISDN Only)
The encryption protocol requires the simultaneous exchange of a prime number and an AES private key between terminals.
For H.320 calls you can choose between two prime number lengths:
The encryption protocol requires the simultaneous exchange of a prime number and an AES private key between terminals.
For H.320 calls you can choose between two prime number lengths:
• High Security (length 1024 bits)
• Very High Security (length 1536 bits)
Note
For IP calls, the System always uses the High Security option with a 1024-bit length.
Most common video communication terminals normally use the High Security prime number length and the 128-bit AES
private key.
