Compute the first two output bytes of the LFSR of degree 8 and the feedback polynomial from Table 2.3 where the initialization vector has the value FF in hexadecimal notation.
Note: The polynomial referred to is .
This solution is verified as correct by the official Solutions for Odd-Numbered Questions manual.
This LFSR derived from this polynomial can be visualised as such:
The sequence generated by , which is , is as follows:
The resulting first two output bytes are .
