CW340_AES_test cannot recover key

Embedded Security Side Channel Power Analysis

Hi all,

I am testing out a new CW340 (specifically the 340-OT kit) with the Husky. The hardware tests pass, but I cannot recover the AES key following CW340_AES_test.ipynb with the supplied AES bitstream (even with >100k traces). I found this forum post that suggests the issue might be some decoupling capacitors that need removed? These capacitors are indeed present on the board. What is the best way to address this issue?

Thanks!
Nathan

Submit a support ticket here to inquire about the cost of removing the decoupling capacitors.
