Cоnsider the versiоn оf CBC-MAC in Fig. 4.1 (Pаge 121 of textbook), with а block cipher hаving a 256-bit key and block length of 256-bit. How many number of block cipher evaluations will be performed to calculate a tag for a message of length 4096? What will be the new value if the block length is reduced to 128-bit? What will be the new value if the key length is reduced to 128-bit? Explain
