Suppose that the plaintext GOOD is encrypted using a 2*2 Hill cipher to yield the ciphertext AKOP. Check if the private key can be found using ciphertext-only attack. Show your work in details

Given the key generation of S-DES in Figure 1, find k1, and k2. The 10-bit key input is (1001000010) 10-bit key 10 P10 3 5 2 7 4 10 19 8 6 P10 P8 LS-1 LS-1 6 3 7 4 8 5 10 9 5 P8 K LS-2 LS-2 15 13 P8 K2
