Chapter B.1 AES-f8 Test Vectors (page 52)

 

Position: j=2

 

IV' XOR j : 595b699bbd3bc0df26062093c1ad8f70

Should be

IV' XOR j : 595b699bbd3bc0df26062093c1ad8f71

 

Reason:

Last byte of IV' = 73, j=02:  73 xor 02 = 71 (0011 xor 0010 = 0001)

 

If my calculator is right, then the values after this position also can't be
correct.

 

Do someone have already implemented it to give me working vextors? Or can
somebody explain me what is wrong on my calc?

 

Thanks,

 

Claudio
