You didnt post the code for AES_package, C128RndkyGen and InvMixRndky.

Are you sure this is the correct code, as it contains syntax errors: ROUT 128 in the process should be ROUT128?

I also note that there are 2 problems with your final process.

1. ROUT128 is not in the sensitivity list

2. It generates latches as you do not assign all bits of RKA128 in all cases. (latches are frowned upon in FPGAs because they can lead to timing problems).
