Question: Consider the monoalphabetic system shown in Figure 8.3 (page 677) and the polyalphabetic system shown in Figure 8.4 (page 678) both from Kurose and Ross

Consider the monoalphabetic system shown in Figure 8.3 (page 677) and the polyalphabetic system shown in Figure 8.4 (page 678) both from Kurose and Ross book. For each system, would a chosen-plaintext attack that is able to get the plaintext encoding of the message the quick brown fox jumps over the lazy dog. be sufficient to decode all messages? Please explain your answer.
