As my current project is about the security that Xilinx embeds in the
Virtex 5 , i have some points that i couldn't understand and really i
need help to advance in my project :

- first how we can prove that really the AES 256 (cbc mode) is used
to crypt the Bitstream +> is it possible to know this by taking
advantages from the .rbt file ? starting from the .rbt file for
encrypted design how can i extract the IV (init vector) , and from
wich part exactly start the enryption ? after the header
information ?

-second , where exactly the key is stored ? articles said " the key is
stored in dedicated memory" ...
the key is stored some where in the surface shown by FPGA Editor or
elsewhere ??

-third , what is the effeciency of the side channel attack to break
AES 256 ?
