No not only other FPGAs, but also other authentication devices like Atmels ATSHA204A or similar devices. So if I understand you right, there is space to secure store only one key in the FPGA. But If I need two authentications with different keys, then I have to take either another FPGA (which would be a bit overkilled) or a separate external authentication device, right? But it should not be a problem to use this key for generating a challenge & response authentication, is this correct?
