I am trying NIST SP 800-22 to test the randomness of 128 bit output in AES, but i always get igamc: UNDERFLOW or Segmentation fault (core dumped) error.
My data file has 128 bit output format, for example as follows:
01101100010001011111011101010011011000000101111001111100010010111011111001010011101101000000111011011100011011101101100011011001
00000000101100000010110001100100101101000010010010110101100111110011011110010000100010001111011110101001100011100000100111000001
Here i have all 100.000 lines with capacity 12.899.967 bytes. I used the tool with the following operations:
./assess 128

Even i tried adjusting the parameters back to 128 but still not working

Can someone give me advice or hints to check the randomness of 128 bit output ?
