You may still The rst SCA attack on the bitstream encryption of (out-dated and dis-continued) Xilinx Virtex-II pro family has been presented in [11], where a full 168-bit key of the underlying triple-DES algorithm could be recovered by a sin-gle power-up of the FPGA ( 70; 000 traces) by searching in a space of 26 for each 6-bit part of the key. Mentioning: 7 - A Cautionary Note on Protecting Xilinx’ UltraScale(+) Bitstream Encryption and Authentication Engine - Ender, Maik, Leander, Gregor, Moradi, Amir, Paar, Christof Building Authenticated bitstream Bitstream can be authenticated using OCM internal memory or by trusting external memory DDR, Xilinx recommends using OCM memory to authenticate the bitstream which is more secure. The bitstream generator in turn generates an In this paper, we introduce novel low-cost attacks against the Xilinx 7-Series (and Virtex-6) bitstream encryption, resulting in the total loss of authenticity and confidentiality. 120 Apr 19, 2020 · Second, the HMAC key KHMAC is stored inside the encrypted bitstream. com Date Version Revision 03/15/2017 1.
