     * Set if null encryption and integrity modes are enabled. If the value of enabled is false

     * the modem must not allow any network communications with null ciphering or null integrity

     * modes.

     * the modem must not allow any network communications with null ciphering (for both signalling

     * and user data) or null integrity (for signalling) modes for 3G and above, even if the

     * network only uses null algorithms. This setting must be respected even if

     * "cipheringDisabled" (as defined in TS 38.331) is in use by the network.

     *

     * For 2G, which does not use integrity protection, the modem must only disallow any network

     * communications with null ciphering.

     *

     * In the case when enabled is false, integrity protection for user data is optional, but

     * ciphering for user data is required. In case of an emergency call, the modem must bypass

     * this setting.

     * ciphering for user data is required.

     * In case of an emergency call, the modem must bypass this setting.

     * Null ciphering and integrity modes include (but are not limited to):

     * 2G: A5/0

     * 2G: A5/0 and GEA0

     * 3G: UEA0 and UIA0

     * 4G: EEA0 and EIA0
