CC1200: Adding AES and on existing MCU + transceiver solution?

Part Number: CC1200
Other Parts Discussed in Thread: CC110L, , CC1101

Team,

We have an existing MCU + CC110L solution.
The idea is to find the simpliest way to add security (AES128 encryption + authentication with key exchange) to it.

I have seen that the CC1200 does support AES (see SWRA183).

-Do we have this features included in any other of our CC11xx/CC12xx transceiver?

-Do we have some TI design making use of the AES feature of the CC1200?
-What would be the level of effort to change an existing design from CC110L to transceiver that enables encryption like CC1200?

I am aware of our CC13xx/CC26xx SOCs but as of now it is not an option.

Thanks in advance,

A.

    Why is CC13xx out of the question since that would probably be the easiest solution?

    CC1200 is the only transceiver that has included AES. 

    I'm not aware of any other AES information than this app note: http://www.ti.com/lit/an/swra483/swra483.pdf

    The SPI interface on CC1101 and CC1200 is equal so a part of the basic code can be reused. But on the other hand, the CC1200 offers more built in features meaning that just porting the code will not be fully optimal since the method of doing things could be different on the two chips. I don't have any numbers on how long time it will take to implement the code for CC1200.
