TANDBERG MPS ADMINISTRATOR GUIDE

Secure Conference (Encryption)

Built-In Encryption

The TANDBERG MPS has built-in encryption of audio, video and data for:

•H.323 meetings (based on ITU standard H.235 v2&v3)

•H.320 meetings (based on ITU standard H.233 and H.234)

Encryption Mode

The administrator decides, when setting up the conference, whether or not a conference shall be in encrypted mode or in unencrypted mode. It is not possible to change the mode when the conference is active with calls.

Encryption Algorithm

The encryption algorithms used in the TANDBERG system are:

•The Data Encryption Standard (DES) with a 56 bits session key

•The Advanced Encryption Standard (AES) with a 128 bits ses- sion key

Typical Setup of an Encrypted Call

Although there are some differences between H.323 and H.320, a typical set-up of an encrypted call can be defined as follow:

1.Establishment of a common secret key and selection of an encryption algorithm.

2.Exchange of keys according to the common secret key and the selected encryption algorithm.

3.Start the encryption.

Common Secret Key

The establishment of the common secret key is done through the computation of a Diffie-Hellman (DH) algorithm. The DH method uses primes numbers of 512 bits length for DES and 1024 bits for AES.

Shared Secret Key

The shared secret key is then used as a key for the selected encryption algorithm, which encrypts the session keys. When the session key is collected by the remote end, encryption of the audio, video and data channels can start.

Establishment of Encryption

The encryption will be established automatically when all end- points in the conference supports encryption, with automatic key generation (and the conference is set up for encryption mode of operation).

Encryption Support

Encryption is supported on all bandwidths. Encryption is also supported for DuoVideoTF and H.239.

For an encrypted conference, all endpoints must support AES or DES encryption.

Encryption Configuration

Encryption is configured when you create a conference or a conference template from the web interface, see MCU Overview > Encryption Mode

•If Encryption Mode is set to Auto, the TANDBERG MPS accepts both AES and DES encryption.

•If Encryption Mode is set to AES, all participants must have AES in order to join the conference.

Scenarios

•If a site entering an encrypted conference does not support encryption, a picture will be shown, informing that the confer- ence requires encryption.

•If a site connected to an encrypted conference starts sending unencrypted data, that site will be taken out of the confer- ence.

•If the TANDBERG MPS administrator has forced the MCU to require only e.g. AES encryption then, all participants must have AES in order to join the conference.

For more information on AES and DES please visit the National Institute of Standards and Technology at www.nist.gov.
