How to enable Ciphering on Amarisoft eNodeB ?

Note: Ciphering is subject to export rules depending on your country so it's disabled by default in your license files

To enable it :

1. Raise a ticket through support.amarisoft.com for ciphering activation
2. Once approved, Amarisoft will generate new license keys
3. Fetch those keys on our extranet and replace old ones with those new keys
4. To enable ciphering for NAS layer, set nas_cipher_algo_pref parameter ( see ltemme.pdf for more details)
5. To enable ciphering for AS layer, set cipher_algo_pref parameter ( see lteenb.pdf for more details)

example of enb.cfg file update: /* RRC/UP ciphering algorithm preference. EEA0 is always the last. */cipher_algo_pref: [3, 2, 1],
