This question in understanding cryptography by Christof Paar

Your task is to compute the S-Box, i.e., the ByteSub, values for the input bytes 29, F3 and 01, where each byte is given in hexadecimal notation.

1. First, look up the inverses using Table 4.2 to obtain values B . Now, perform the affine mapping by computing the matrix-vector multiplication and addition.

2. Verify your result using the S-Box Table 4.3.

3. What is the value of S(0)?
