16.18.3.3 Changing Keys Seamlessly
Starting point: The encryptor sends encrypted data to the decryptor. The odd key is active. Both
have their encryption mode set to "On".
Steps:
1. Enter the Even key in the decryptor.
2. Enter the Even key in the encryptor.
3. Select the Even key in the encryptor. The encryptor starts to use the even key.
An alternative is to turn the encryptor off, change the keys on encryptor and decryptor
and turn the encryptor back on. The drawback is that the content is not encrypted
during the time needed to change all the keys.
16.18.3.4 Adding a Receiver to the Network
Starting point: The encryptor sends encrypted data to several decryptors all using the same
content key.
Steps:
1. Enable AES
2. Select the correct Key Strength
3. Enter the correct content key into the decryptor of the new receiver.
